This situation is the reason for having specific versions in all
dependencies. Is there a scenario where this wouldn't be enough?

The goal is to have no such overlap. The problem is to recognise when
such an overlap occurs. There are two situations that ArchHaskell
needs to notice:

1. A Haskell package in core/extra/community is updated to a new version
2. A Haskell package is added to core/extra/community

Is there some way of (semi-)automating this already?
