It would be nice to have guile2.0-git, but note that it does not *have*
to exist: ‘package-for-current-guile’ returns #f if none of the packages
exists, and (guix build pull) skips modules that lack their
dependencies.

So I would first suggest to re-add (guix git), and later see with
Amirouche et al. what could be done to get Guile-Git on 2.0.

Does that make sense?

Thanks,
Ludo’.
