This will force a change to xfstests at a minimum.  And I do know of users who

If it's only a few tests that fail, I wouldn't worry about it, and the

But if there are real user concerns, we may need to have some kind of
compat code. Because of the whole "no regressions" thing.

What would the typical failure cases be in practice?
