With cycle-with-rc, that does allow *beta* releases to be done at any
point during the cycle. But those would be marked as b1, b2, etc.
releases. This allows those that want to try out upcoming features to
grab them if they want them, but would prevent anyone else from
accidentally picking up something before it is quite ready.

I'm guessing this might not be what you are looking for though.

We do have another release model called cycle-automatic. This was
introduced for tempest plugins to just do a release at the end of the
cycle to make sure there is a tag to denote the tempest version the
plugin was originally developed for. Since some plugins are being picked
up more often downstream, this model does allow for additional releases
to be proposed at any point during the development cycle.

We will need to discuss this as a team to see if this makes sense for
non-tempest plugins. It was intended only for those types of
deliverables. I just mention it here as something that we do have in
place that might be adapted to fit what the team needs. But we also need
to consider what we are communicating to downstream consumers of our
releases, so I'm not entirely sure at this point if it makes sense, or
would be a good thing, to allow other types of deliverables to use this
model.
