This doesn't work, because downstream users of the upstream code have no
way to know what upstream considers as the frozen-working-version. With
RC1, we do know.

Again, can we have a middle-ground where we have only a SINGLE rc
release before the final one? For downstream distros (like Debian) I'd
be easy to integrate patches to fix problems on top of this unique RC.

Last, the RC doesn't have to be cut out of a stable branch. If that is
the issue (ie: backporting to the stable branch before the release is a
high cost), then the RC could be cut from master... Whatever is the best
workflow upstream, I don't mind, as long as we have pre-release to eat
for 1/ downstream distro 2/ config-management projects like Kola / OSA /
puppet-openstack.
