Deployment tools:
* Lee is working on TripleO support for extracted placement and estimates 3 more weeks for just deploy (base install) support to be done, and at least 3 more weeks for upgrade support after that.

Can you (or Dan?) clarify if spanning the release boundaries is usefully specifically for tooling that chooses to upgrade everything at once and thus is forced to run Stein nova with Stein placement?
And if someone were able/willing to run Rocky nova with Stein placement (briefly) the challenges are less of a concern?
I'm not asking because I disagree with the assertion, I just want to be sure I understand (and by proxy our adoring readers do as well) what "ease" really means in this context as the above bullet doesn't really explain it.
I didn't go into details on that point because honestly I also could use some written words explaining the differences for TripleO in doing the upgrade and migration in-step with the Stein upgrade versus upgrading to Stein and then upgrading to Train, and how the migration with that is any less painful. I know Dan talked about it on the call, but I can't say I followed it all well enough to be able to summarize the pros/cons (which is why I didn't in my summary email). This might already be something I know about, but the lights just aren't turning on right now.
a general questionon this topic. is there any update on supprot for deploying and upgrading to extracted placnement with other deployment tools the main ones beyond triplo that come to mind are kolla-ansible, juju, openstack-ansible, openstack helm there are obviously others but before we remove the code in nova i assume we will want to ensure that other tools beyond devstack, grenade and tripleo can actuly deploy stien with extracted placemnt and idealy upgrade. was this covered in the placement extration meeting.
