One thing I probably didn’t explain clearly is that yes, the circular
dependency issue is one we have to solve.  For years, I hope we could
avoid it but experience has shown that no, it’s a problem we did have to
address.

One example is Guile-GnuTLS being built from a Git checkout.  Another
one is Hurd packages in commencement.scm built from a Git checkout.  We
had to go to great lengths to avoid ‘git-fetch’:

  https://issues.guix.gnu.org/64708#6

More and more software is built from Git checkouts rather than tarballs.
In the long run, we won’t be able to guarantee that none of the
dependencies of ‘git-minimal’ takes its source via ‘git-fetch’.

This is especially true if we want to move away from Autotools-generated
tarballs and instead run ‘autoreconf’ ourselves on pristine source.
