And the evidence for "most people" would be ... ? ;-) It hasn't been
raised before, despite filters working the way they do since Python
2.3 ...

And I wonder, would any of those people be willing to accept the
performance impact of the change? I'm not sure how big the impact
would be, but it does involve another hierarchy traversal and
additional calls to the ancestor filters.
