This discussion is about stable branches. Maybe early in a stable branch's
life there are lots of commits, but as it grows older, the number of
commits made to a stable branch certainly isn't 1 per day.

It seems from other discussions that there is little coordination between
distros in the first place, and that is only beginning to improve now, but
only between close relatives (Ubuntu & Debian, RHEL & CentOS & Fedora,
etc.). If that's the case, the work to improve coordination, including
sharing repositories, etc. would seem to alleviate this concern regardless
of coordinated release tagging.

Not every bug fix gets backported during the life of a stable branch. At
least in Glance, the majority of backports are security fixes and the rest
are rather serious bugs that significantly break the service or prevent
the use of the service. Last I checked, bug fixes needed to meet a certain
set of criteria before a backport was created. I'm fairly certain this
hasn't changed, but I admit that I haven't checked for changes in the last
That said, I know you've said in the past that you do most of your
packaging in your free-time because it's not part of your job
responsibilities. I know the same is true for a bunch of OpenStack's
packagers (including the Gentoo packager). This is what makes me torn on
whether or not we should totally drop stable point releases. As someone
who spends the majority of their free time supporting other software
beyond OpenStack, I understand how insulting it is to be told you have to
do more work in the time that you're volunteering.
This makes me more in favor of letting projects cut their own point
releases for stable branches. That said, I don't think it will alleviate
your concerns of guaranteeing that 2015.2.1 of X works with 2015.2.1 of Y,
but if these truly are only bug fixes, then I think the guarantee is
implicit in the branch. I've only been around for a little less than a
year though, so I have no memory of a backport in one service breaking
