It would be possible to split off bytestring, containers, prettyprinting
and printf now (though some of them would still be in GHC's core, as
they're used by Cabal).  Splitting the rest is more complicated than
picking GHC.*, as there are many interdependencies.  But we could do
the easy part now.

This would be a violation of the "no interface changes in minor releases"
rule (though at the package level rather than the module level, assuming
the split fps was core), but I think there's a strong argument for it,
since development of this package is continuing outside base.
