It would be unreasonable for a single tester, but "the more testers, the
Which doesn't mean the group of testers will perform _all_ of the
(re-)tests. It means: the more testers get a chance to apply Test Updates
*and* continue using their systems normally for a few days, the more
likely it could get that some will notice issues at run-time, boot-time,
compile-time, to mention a few.
That's why I think there's reason to be very careful and sometimes even
prefer a +0 (with a comment) over a very early over-ambitious +1.
And guess what happens in non-critpath updates after 7 days and _no_
feedback. Packagers push the update manually. Sometimes with broken
deps. Sometimes the testing starts no sooner than when the update arrives
in the stable updates repo and the first real user becomes the "guinea

about a single bz ticket.

That's understood, of course.
