Maybe I missed something but “guix gc” handles what we implement, no? :-)

Well, I run “guix gc” when I need some space.  And this
“maybe-run-git-gc” does exactly that: collect some spaces when I need
them.

For me, they are part of “guix gc” and not part of some update.


Aside, re-thinking about other features, I am consistent with other
comments I made when introducing ’maybe-remove-expired-cache-entries’;
see <https://issues.guix.gnu.org/45327#4>.  And consistent because most
probably I still think the same: cache cleanup should be handled by
“guix gc” and not by the commands themselves.  And maybe we are having
the same discussion. ;-)

Maybe I misread, somehow it appears to me that you miss the key part: I
choose when some extra work is done and I keep “guix pull” and “guix
time-machine” as fast as possible.
