I'd expect the main consumers to be os and os.path, and would honestly be surprised if we needed many explicit invocations above that layer, other than in pathlib itself.

I made a toy implementation to try this out, and making os.open support it does not get you builtin open "for free" as I had suspected; builtin open has its own type checks in _iomodule.c.

Probably anything not implemented in pure python that deals with filenames is going to have to have its type checking revised.
