I agree that you went out of your way to be inclusive, but having a
single PTL for a group of competing alternatives is a bit weird. As far
as "preventing blooming", that's something we've heard from the Board of
Directors (as part of an objection to calling the TripleO program
"OpenStack Deployment").

Note that I'm only advocating that Monty's layer #1 things would be
released in an integrated manner on a time-based schedule. That's not
"all our things". All the other things would be released as-needed. That
lets us focus on cleaning up interfaces between layer #1 and other
things first. Swift is doing the right thing today because its
loosely-integrated with layer #1 (and has a clean interface for doing
so). So Swift is doing the right thing for an non-layer#1 project.

Once our layer#1-internal interfaces are simple/stable enough that we
can safely compose something that works at any time by picking the
latest version of everything, we can discuss the benefits and the
drawbacks of the "common release" model. I still think there are huge
community benefits to sharing the same cycle, and gathering around a
common "release" that can be advertised and consumed downstream... as
far as layer #1 is concerned.
