@Yhg1s - I've tagged you on the review as I'd like your opinion on whether this qualifies as a bugfix for Python 3.12. It's considered a security issue by some (that's how it was reported to me), but since the issue was introduced in 3.12, there's no need to backport it to security-only Pythons.

Are you okay with including this change as a bugfix for Python 3.12 (and by extension 3.13), or would you rather keep the "always false" behavior for 3.12 and 3.13?

Sorry, @jaraco, I could not cleanly backport this to 3.12 due to a conflict.
Please backport using cherry_picker on command line.
