That's "should", not "must".
Also, I thought people did undocumented things with distutils, and we
had to support these undocumented uses?

I don't see how adding "expected failures" solves anything. It's not
clear why this failure should have been expected, rather than a bug.
A "commit adding problem" should be fixed or reverted; marking some
failures expected is just dodging the issue.
