Since the Cuirass job remains, I don't think it is really any extra
work or not to recreate the branch as needed, if that is preferred.
I'll defer to whatever people want, we can always change our mind if
anything comes up.

As for the pace, on the main 23.1.x releases we see about 2 weeks
currently. If that is a bit fast I think about once a month is a
reasonable pace, maybe depending if it is a small bugfix release or
what other changes we may need causing other rebuilds to be grouped on
the branch. We can slow down if major changes are introduced, but
seems Mesa is moving along without breaking changes or major changes
in building/support these days.

As you can follow along on <https://issues.guix.gnu.org/64369> within a
couple of days x86_64 and i686 had good weather (though I can't see
specifically what may have broken yet) while as we'd expect things
like aarch64 are still churning away. The speed of this build job
might determine how fast we can go anyway, but waiting too long will
mean a new minor release to build :)
