This looks like a duplicate of #12029. The delays on addressing that bug seem to indicate that initially there was a fairly substantial performance cost for all exception handling paths when ABC friendly checking was performed, but that was at least partially due to a bug in those code paths that didn't bypass the ABC machinery in the simple subclass case.
That said, I'm not sure it wouldn't cause other performance regressions (I made a comment to that effect on the original bug). |
