Thanks for writing this up, this aligns pretty well with what I
recall. Some additional notes/comments within.

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.

This is ready to go with https://review.openstack.org/#/c/631308/
and https://review.openstack.org/#/c/618708/ . Both need one more
