Preferably nothing. :-) There's been too much discussion already.

Name and placement: I think it belongs in os, and os.PathLike sounds like a
fine name. (I'm surprised that os.DirEntry doesn't exist.)

Typing: do you want it to be a generic class? If not, the types can be left
out of the stdlib and only put in the stub (though you can show them in the
PEP of course).

If you want it to be generic we have more work to do. I'm out of time now
but we can discuss that after 3pm today.
