Apologies for not contributing so far, this month is busy for me.  I
think the slow feedback loop with ci.guix is one of the main reasons
people don’t contribute much.  Perhaps the whole process is also unclear
to people who’re not seasoned contributors?

Yes, that was the goal, but again, ci.guix got in the way by not
providing quick feedback.  Then there were holidays, and then I was busy
with other things, as I guess is the case with the other people who
previously looked into it.

My assumption was that an ungrafting branch would be easy to handle:
trivial changes, no breakage.  But it’s not that simple: we met actual
breakage (Marius fixed non-trivial things), and again, the feedback loop
was too slow.
