 ## Phase 4 Advancement Criteria
 
-`wasi-messaging` should have at least two implementations for both open source message brokers (such
-as Kafka, or NATS) and two for cloud service providers
+For `wasi-messaging` to advance to Phase 4, it must have at least two independent implementations 
+for open-source message brokers (such as Kafka, NATS, MQTT brokers) and two for cloud service providers 
+(e.g., Azure Service Bus, AWS SQS).
 
 ## Introduction
 
-The wasi-messaging interface is a purposefully small interface that is focused purely on _message
-passing_. It is meant to express the bare minimum of receiving a message and sending a message along
-with an optional request/reply interface that allows for message based APIs and/or RPC.
+In modern software systems, different components or applications often need to communicate with each other 
+to exchange information and coordinate their actions. Messaging systems facilitate this communication by
+allowing messages to be sent and received between different parts of a system.
+
+However, implementing message-based communication can be challenging. It requires dealing with the details
+of message brokers, such as connection management, channel setup, and message serialization. This complexity
+can hinder development and lead to inconsistent implementations.
+
+The `wasi-messaging` interface is a purposefully small interface focused purely on message passing. It is
+designed to express the bare minimum of receiving a message and sending a message, along with an optional
+request/reply interface that allows for message-based APIs and/or RPC.
+
+By providing a standard way to interact with message brokers, the `wasi-messaging` interface aims to simplify
+this process, hiding the underlying complexity from the user. This aligns with the broader goals of WASI by
+promoting interoperability, modularity, and security in WebAssembly applications.
 
 ## Goals
 
-The messaging interfaces aim to address the need for a standard way to handle message-based
-communication in modern software systems. In complex software systems, different components or even
-different applications need to communicate with each other to exchange information and coordinate
-their actions.
-
-However, implementing message-based communication can be challenging, as it requires dealing with
-the details of message brokers, such as connection management, channel setup, and message
-serialization. The messaging interfaces aim to simplify this process by providing a standard way to
-interact with message brokers, hiding the underlying complexity from the user.
-
-As mentioned in the introduction, the primary goal of this interface is to focus on message passing.
-The only guarantee offered is that publishing a message is handled successfully. No other guarantees
-are made about delivery of the message or being able to ack/nack a message directly. This is by far
-the simplest representation of the complex problem of message-based communication. The idea behind
-this is straightforward. If something can pass or receive a message, that paradigm can easily be
-expanded upon by future interfaces (like a queue-based work interface). Also, many pieces of
-business logic can implement something simple like the message handler in this interface and have
-details such as work dispatch and queuing be backed behind that implementation, invisible to the
-business logic (and/or shared with multiple business logic components). Conversely, anything that
-can send a message can easily be passed into a queue (such as a Kafka stream or NATS JetStream)
-without the knowledge that it is being sent into a queue. Essentially, this gives us the most basic
-foundation of messaging which we can add more to, or propose additional interfaces as the use cases
-emerge.
+The primary goal of this interface is to focus on message passing. The only guarantee offered is 
+that publishing a message is handled successfully. No other guarantees are made about the delivery 
+of the message or being able to ack/nack a message directly. This minimalist approach provides the 
+most basic foundation of messaging, which can be expanded upon by future interfaces or proposals as 
+use cases emerge.
+
+This simplicity allows:
+- **Ease of Integration**: Components can easily implement the message handler in this interface, 
+with details such as work dispatch and queuing handled behind the scenes, invisible to the business logic.
+- **Flexibility**: Anything that can send a message can easily be passed into a queue 
+(such as a Kafka stream or NATS JetStream) without the knowledge that it is being sent into a queue.
+- **Extensibility**: The paradigm can be expanded by future interfaces (like a queue-based work interface) to handle 
+more complex messaging scenarios. By focusing solely on message passing, the wasi-messaging interface simplifies the 
+development of interoperable WebAssembly modules that can communicate over various messaging systems without being 
+tied to any specific implementation.
 
 ## Portability criteria
 
-The main portability criteria on which this should be judged is whether a component can receive and
-send a message from all major messaging systems. This includes anything implementing message
-standards like MQTT and AMQP, specific technologies like NATS and Kafka, and cloud provider
-implementations like Azure Service Bus and AWS SQS. This _does not_ mean it implements the full set
-of features of each of the messaging systems. In fact, it is expected that most implementations will
-need to do work to adapt their system to this interface (i.e., in Kafka, you'd have to mark the
-message as completed once the call to `handle` returns). As mentioned above, this should still be
-completely compatible with any more advanced use cases of the various message systems. For example,
-if you have a queue of work that is currently being handled by a pre-existing piece of software
-outside of Wasm components, a component could use this interface to publish messages that get
-ingested into this queue. Another way to state the portability criteria is that this implementation
-should not break the possibility of a component consuming this interface to be integrated in with a
-more advanced messaging use case
