I'm not a fan of the current proposal. I feel like the discussion jumped into a
policy/procedure solution without getting much more feedback from operators.
The room heard "ops want LTS" and we now have a new governance model to work
out.
What I heard from ops in the room is that they want (to start) one release a
year who's branch isn't deleted after a year. What if that's exactly what we
did? I propose that OpenStack only do one release a year instead of two. We
still keep N-2 stable releases around. We still do backports to all open stable
branches. We still do all the things we're doing now, we just do it once a year
instead of twice.
Looking at current deliverables in the openstack releases repo, most (by nearly
a factor of 2x) are using "cycle-with-intermediary".

release-model * | cut -d ':' -f 2- | sort | uniq -c
44 release-model: cycle-trailing
147 release-model: cycle-with-intermediary
37 release-model: cycle-with-milestones
2 release-model: untagged
Any deliverable that using this model is already successfully dealing with
skip-level upgrades. Skip-level upgrades are already identified as needed and
prioritized functionality in projects that don't yet support them. Let's keep
working on getting that functionality supported across all OpenStack
deliverables. Let's move to one LTS release a year. And let's get all project
deliverables to start using cycle-with-intermediary releases.
