That would be option B.

The main issue with B is that it doesn't work well once server component
versions start to diverge, which will be the case starting with Liberty.
You can't tag everything with the same version number anymore. We
already couldn't (with Swift using separate versioning), but we worked
around that by ignoring Swift from stable releases. As more projects opt
into that, that will no longer be a possible workaround.

So we could do what you're asking (option B) for Kilo stable releases,
but I think it's not really a viable option for stable/liberty onward.

It also removes the stupid encouragement to use all components from the
same date. With everything tagged at the same date, you kinda send the
message that those various things should be used together. With
everything tagged separately, you send te message that you can mix and
match components from stable/* as you see fit. I mean, it's totally
valid to use stable branch components from various points in time
together, since they are all supposed to work.

So I totally get that we should still have reference points to be able
to tell "this is fixed in openstack/nova stable/liberty starting with
12.1.134post34" (or whatever we settle with). I totally get that any of
those should ship with relevant release notes. But that's about all I
think we need ?
