Surely you’d agree that it would suck though: depending on two Git
implementations because one doesn’t have a proper API and the other one
lacks a bunch of features.

It would also be pretty bad for closure size:

--8<---------------cut here---------------start------------->8---
$ guix size guile-git | tail -1
total: 106.6 MiB
$ guix size guile-git git-minimal | tail -1
total: 169.8 MiB
--8<---------------cut here---------------end--------------->8---

It’s also not clear concretely how we’d add that dependency.  Try
invoking ‘git’ from $PATH and print a warning if it doesn’t work?
But then, what about applications like Cuirass and hpcguix-web?

Tricky, tricky.
