FWIW, I don't think that splitting base into multiple libraries would
achieves much, it would likely raise the cost of coordinating

I do however agree that perhaps separating base from GHC could be a good
idea, if GHC could ship a smaller foundational library with primops, ...
and `base` evolved somewhat independently.

However that too has potential drawbacks, because packages would be more
likely to have non-overlapping version bounds on a separately evolving
base...  Probably manageable, but something to keep in mind.
