And the other question could be turned into whether to make str and bytes also PathLike in subclasshook. No, for two reasons. - most str's and bytes' are not paths;

True. Well, at least most str and bytes objects are not meant to be used as paths, even if they could be.

- PathLike indicates a rich-path object, which str's and bytes' are not.

This does not count as a reason.

If this were called pathlib.PathABC, I would definitely agree [1]. But since this is called os.PathLike, I'm not quite as sure. Anyway, including str and bytes is more of a type hinting issue. And since type hints will in also act as documentation, the naming of types is becoming more important.

[1] No, I'm not proposing moving this to pathlib
