Re: packages with orphaned instances only

This would be analogous to automatic import of instances at a package level.

However the adapter package might import other heavyweight packages that someone may not want to have.

Yes, that's a good analogy. Basically a way to ensure consistent instances not just in a single program, but across all of Hackage (modulo opt-out capabilities).

Presumably the only dependencies for adapter packages would be the two packages they are adapting between in almost all cases?

I am uncertain. Someone might choose to move an instance to an adapter package just because it needs a critical additional import. Btw. what is the opposite of an orphan instance?
