I thought about providing package ghc-transformers-instances, that will
provide instances for transformers's type classes for user. So
ghc-tf-instances will depend on current ghc, and current transformers that
could be provided by user environment.

As transformers usage are quite limited in ghc, and it's really relevant in ghc-bin, it's possible to duplicate the code, and provide required fixes in ghc-bin.cabal. As a result ghc uses it's own MonadIO, MonadControl and Strict State, and ghc-bin.cabal (ghc/*) uses ones from transformers.
...but doesn't this effectively mean that the instances provided by the `ghc` package are of little use or rather can't be easily combined with code that builds on top of the original `transformers` classes everyone else uses?
