AFAIU this would also impact all people packaging haskell, whether
they use HP or not.  Including these packages in GHC will most likely
mean that improvements to these packages only become available to end
users when new versions of GHC arrive.  I'm not sure how quickly these
packages move, but I think that would be an unfortunate situation
indeed.

How tight is the tie between ghc and ghci, would it be possible to
separate ghci and ghc?

I invented the term Object-Oriented, and I can tell you I did not have
C++ in mind.
