Standalone MediaCollection classes

[nickfls]

A lot of times a specific media collection type is reused: like an Avatar which is single, located in public, allow for only accepts images, generates responsive image, etc or specific upload collections shared between different models

I tried to either extend MediaCollection - and I need to overload constructor; or have a wrapper - which would require resolution logic.

Would it be possible to define MediaCollections as separate classes (however they are defined) and check if addMediaCollection() receives a MediaCollection instance, just add it instead of ::create($name)?
