Forking is much worse than using multiple vcs's, and if we don't fork,
anyone working on those libraries will have to use git at least to get GHC
HEAD to check that they're not breaking it.  And clearly GHC developers
outnumber developers of other implementations.  (I don't think a move
to git will lead to more GHC developers, but I buy the interns argument.)

My concern is that there are rather more developers of libraries and
assorted other packages, and this will place an arbitrary divide across
those.  Unless everyone moves to git, of course.
