Gnocchi is applying "release early, release often" so there is no really
any big cycle like older OpenStack projects. Major or minor versions are
released from time to time, and more often than 6 months in general.

It would be good to support that as being *normal*, not "potentially
incorrect and random"!

And by the way, it's a shame that the release:has-stable-branches cannot
be applied for release:independent. We have stable branches in Gnocchi,
we cannot have that tag currently for that only reason. Worse, we often
hit issue about assumption made about how projects are released. See my
recent thread about the devstack-gate based jobs failing for stable
branches.

It'd be awesome to free those projects and support more flexible release
schedule for project having a different velocity.
