In the commit description you mentioned that "the base feature of what this test
encompasses will instead be migrated over to a full separate gate/check job that
will be able to handle the more complex tasks of ensuring schema upgrades make
sense."

As I understand, a gate test which upgrades the DB to the latest version and then
runs tempest on the old release would cover the cases which the unit test covered.
Is this what you had in mind?

Do you think I can start working on it, or maybe we should synchronize on what the
final approach should be beforehand?

Can you elaborate more about what the ideas of testing schema changes were
at the midcycle?

What especially interests me, is whether you discussed any ideas which might be 
better than just running tempest on keystone in HA.

I'm sorry I couldn't take part in these discussions.
