Geolocation.Options takes unitless values instead of Times

[BrianHicks]

The record for Geolocation.Options has the following structure:

type alias Options = 
    { enableHighAccuracy : Bool
    , timeout : Maybe Int
    , maximumAge : Maybe Int
    }

The documentation specifies these values are in milliseconds. I'm curious why this isn't implemented using a Time instead. Wouldn't it reduce mistakes to use an interface that encodes the unit as well as the value?

-- unitless integers
{ defaultOptions | maximumAge = Just 30000 }

-- Times
{ defaultOptions | maximumAge = Just (30 * Time.second) }
