I wasn't worrying about the 3.5.0rc "branch", but, yeah, we could probably improvise ones for that as you suggest. So, buildbots would be: 3.5 branch (->3.5.1 as of beta1), 3.5rc (as needed from rc1 to final), along with the current 3.x (->3.5.0 today, -> 3.6.0, as of beta1), 3.4, and 2.7 buildbots.

I like the idea of experimentally trying the push workflow but, if we are all doing our jobs right, there should be very few changes going in after rc1 so most committers won't need to push anything to the 3.5.0rc repo and, if for some reason they aren't able to use Bitbucket, someone could do it for them.  In other words, while nice, the use of Bitbucket is not a critical feature of Workflow 1.  I think 1 is the best choice with or without the use of Bitbucket.  But we should also recognize that adopting it can make more work for committers fixing bugs over the next few months (between beta1 and final), as we need to consider testing and pushing each fix to default (for 3.6.0), 3.5 (for 3.5.0 until rc1, then for 3.5.1), 3.4 (for 3.4.4), and/or 2.7 (for 2.7.11).  That's the tradeoff for allowing feature work to be committed, integrated, and tested during the beta and rc periods.

Workflow 0 = -1
Workflow 1 = +1
Workflow 2 = -0.5
