It's different in that these wouldn't be X+1.0.0b{1,2,3} but X.{1,2,3}.0. For a
more concrete example, it would be something like:
If Glance were to do this, for mitaka, then instead of releasing 13.0.0b{1,2,3}
it would release 12.{1,2,3}.0 at each milestone. According to semantic
versioning we could land features in those releases but we'd be communicating
more strenuously to consumers that this was really meant to be a release that
would be a very very very smooth upgrade experience as it really focuses on
stability.

Right, I would suspect that this would be because the releases are beta
releases and no one wants to spend the time to use/stress them too much. :-/

Right. I know the downstream teams are small which is why I noted that having a
release cadence of actual concrete releases on those milestones instead of beta
releases might cause too much work. If it's one service doing that, perhaps not
but if several do that in an even remotely synchronized manner, I can imagine
that would introduce a lot of work.
Either way, my idea was already shot down because it would mean projects would
be changing their release model frequently and that's not desirable.
