The changes have introduced deprecation warnings in tests. It seems https://github.com/python/cpython/blob/ad106c68eb00f5e4af2f937107baff6141948cee/Lib/test/test_pathlib.py#L1937 is not covered.

Also it will be nice to point to the line causing deprecation instead of the library soruce code that will help users identify the deprecated usage. Using stacklevel=2 might help here https://docs.python.org/3/library/warnings.html#warnings.warn
