That’s the cause, yes, but considering that the library works for 3.10+ and not just 3.13 or 3.14 (if PEP 467 gets approved), I don’t think that would help a lot with the current implementation of the library.
It is a nice-to-have feature that I’m requesting. This StackOverflow question has ~83k views and ~70 upvotes as of writing, so I can safely say that the problem is somewhat common.
