Actually, a change I'd like to see is just make sure that no modules
re-export anything that prelude exports.
Do you have any examples of this?
Data.List has a lot of them.  Others include:
Control.Monad: Functor(fmap), Monad((>>=), (>>), return, fail)
Data.Functor: Functor(fmap)
Data.Maybe: Maybe(Nothing, Just), maybe
Data.Ratio: Rational
Maybe I misunderstood the concern.

For me it looks more like Prelude re-exporting stuff from those modules, which
makes sense.

Would you prefer Data.List randomly lacking lists functions on the basis that
they are exported by Prelude?
