Good point, I hadn't considered grenade. While we don't expressly
mention the platform used for upgrade tests as part of the PTI, you
are correct that we deploy release N-1 on the default node type for
release N-1, then upgrade it in-place to release N and run a battery
of tests against it. Technically we do test the new release on the
old platform (at least for projects which tests their changes or are
otherwise exercised by grenade), even though the PTI says we can
drop support for the Python version on that platform.

If someone wants to work on running grenade on centos-8-stream nodes
for yoga, we could ensure that's still a viable upgrade path the
same way.
