ISWYM.

That might be nice, if it were very little osstest-development effort to
make it happen, but I think it isn't going to be a small effort and
running tempest and seeing what happens seems like it would be good
enough anyway.

But in the presence of stable backports we may not get the exact same
set of commits from one day to the next, despite cloning the exact same
devstack revision, I think?

Right.
