Feature or enhancement

We could implement / reuse the same fast paths that we did for os.path.* in #101324 for pathlib.Path.*. It will require a little more work, since the pathlib.Path API can return OSError under certain circumstances, whereas os.path would return False in those cases.

Pitch

We saw a 12-25% speedup doing this for os.path. It would be unfortunate if people chose the lower-level API for performance reasons because pathlib.Path didn't match it in performance.
