Comment (by refold):

 If it was something like `text` or `directory` (which comes with GHC), or
 even `Cabal` itself, where it makes sense to upgrade them if you're
 running an old GHC version, I'd be against that as well. But in the case
 of a small number of wired-in non-upgradeable libraries like `base` and
 `integer-gmp`, an additional obstacle like this is actually a ''good''
 thing. The solver in `cabal-install` also
 [https://github.com/haskell/cabal/blob/master/cabal-
 install/Distribution/Solver/Modular/Solver.hs#L127 goes out of its way] to
 prevent users from trying to reinstall `base` and `integer-gmp`.
