The PVP provides the framework that allows flexible version
specifications for dependencies.

Assuming the spirit of the PVP is followed, you can ignore the D-level
version numbering, and depend on C-level numbering in a cabal file.
That generally allows bugfix releases of your dependencies to be used
without any changes to your code or cabal file, while telling cabal
that API-breaking changes (marked by the higher version number slots)
do not satisfy your application's requirements.

This is far from foolproof, but it is very convenient when it's followed.
