Comment (by duncan):
For cabal-install to update a whole bunch of packages correctly we would
need more than just ghc-pkg update, if we implement this check. We would
need to be able to register/update a whole batch of packages at once. Or
we'd have to unregister each package and all its dependencies (in reverse
order) and then re-register them all (assuming we did actually update them
all).
