How to make Views exporter specific?

Problem Statement

Hello, in the SDK, you can have multiple exporters per meter. Currently we use Views to drop metrics and attributes on a global level. At the same time, we allow our users to define their own exporters. We want to allow dropping metrics and attributes per exporter level because each backend has different expectations. Unfortunately, we haven't found a way to do this in the SDK because views only provide access to the instrumentation information.

I think this is something that needs to be handled at the specification level.

Can you use the OTel Collector to drop metrics and attributes instead of doing it in the SDK?

We don't always own the collector. Customers can use their own or SaaS and it also might not be always feasible. More importantly, we want to avoid any overhead in the service. We're developing a high performance API Gateway.
