You're missing my point: What good is it to do a release when you
yourself consider it of such poor quality that you advise others not to
That has nothing per-se to do with who uses that release and whether you
build it in OBS or locally.

I don't understand that question. The proposal, as I understood it, is
to shorten the release cycle by one month, doing six instead of four
releases. How could there be an improvement by leaving it as it is? My
fear is that the change will make it _worse_, i.e. no improvement but
rather risk of more regressions by switching to _two_ months.
In this very same -rc4 thread I reported one such regression, and
luckily a patch was quickly prepared to address it. It's not yet merged
despite tested - review also takes time.

Agreed. And my point was that testing takes time. Increasing the release
frequency shortens the time for testing of each release.

Many custodians are volunteers. You can't force them to test boards at a
pace you dictate to them. Also, more frequent releases also increase the
chances of a custodian/maintainer being on vacation during a release.
And a working, say, BeagleBone doesn't make the user of a random other
board any happier. ;-)
