Yeah, given that you have to go out of your way to create a path object for an alternate platform, this makes sense - the "I know what I'm doing" indicator is calling pathlib.Pure[Windows|Posix]Path instead of ""pathlib.PurePath in the first place, and so __fspath__ can just do its thing as a pure text-based operation, without worrying about the current platform.
