Your mean from the Guix user using Haskell point of view where they
already has this huge “guix size cabal-install”.  What about the Guix
users point of view who are not using Haskell?  That’s why Guix does not
depend on per language tools for the importers.  Without speaking that
Guix runs on many architectures other than x86_64.

Well, Guix provides an extension mechanism, see GUIX_EXTENSIONS_PATH.
Maybe it is the entry point for what you would like to have.

Yes, I guess.
