Have you changed your mind since our previous discussion, or just
forgotten it?  (Or did I screw up and revert the wrong commit?)  See

This returns us to pre-3.15 behavior so shouldn't introduce any new

Fundamentally the problem is that we're returning an error in cases that
shouldn't succeed, and rather than replacing one incorrect error by
another it seemed better to wait for a proper fix.
