But ... I want better than the stability guarantees we have today!

I want to obsolete those messages to quality-discuss with "new failures"
because it should not even be possible for master to get into a state where
regression tests have regressed (except for flakes or external
dependencies).

People do "continuous testing and integration" these days.  Set up your
integration pipeline so that it is always running.  The pipeline
automatically promotes changesets to master when all tests pass.  Easy!
Then every master changeset is equally stable to a "promoted build".

In principle, the same could be accomplished via running every single
commit through a jprt-like process, but I'm afraid that would be too
expensive.  Back in my day, full build + test took on the order of 10
hours, so changesets would need to be batched, or you need to throw more
hardware at the problem (give every changeset a dedicated machine for
testing?)
