The haskell-build-system respects a #:haskell argument like so:
(arguments
`(#:haskell ,ghc-8.8 ...))
That way you don't end up bumping the default ghc for everyone while
updating one package.
I tried your definition with ghc@8.8 as above and some new packages were
not in constraints. Can you go from there and update the
"update-constraints" phase as you go? Maybe that will be enough.
Thanks!
