This is the only approach that is sane...

We would probably consider a backport of that to DevStack Juno, but
Icehouse is effectively EOL and we will be removing that branch soon (days
or weeks, not months).

No.  Even on master you may have issues trying to run a early cycle project
with a late-cycle DevStack.  DevStack evolves to meet the needs of the
projects as they develop.

That Tempest fix is pretty straightforward, with only the one code block
move not being a "skip this if project is not enabled" check.  With
Icehouse EOL, there will be no additional updates so maintaining that
backport in a local private branch should not be a big deal.  You will need
that anyway to keep using icehouse after we remove that branch from the
DevStack repo.
