Fully agreed if we can't fix them. But we also need to strike some
balance for otherwise we can never enable we self-tests. And I
absolutely want those enable to have the best possible regression
testing coverage. E.g. every time we add a substantial amount of new
checks to the modeset state checker it takes 1-2 releases to settle
all the fallout. But we're backporting all the fixes, except when
they're too invasive (in which case we disable the check temporarily
or restrict it).
