[issue44200] Recommend importlib.abc.Traversable users to implement __fspath__

Filipe Laíns added the comment: CompatibilityFiles would use this. We could add a dispatch for that too, but that's 2 different cases now and `os.PathLike` would be able to handle both. -- ___ Python tracker

Jason R. Coombs added the comment: > I think `as_file` should learn to behave like `path`, if `__fspath__` is > available, it will use that path. Oh, that's an interesting idea. And that's effectively what happens

Filipe Laíns added the comment: That's why I said it should be optional. If the object can implement it, it should. `pathlib.Path` certainly can, `zipfile.Path` can't, and that's alright. If the Traversable does not represent a path on the file-system, it does not make sense to implement

[issue44200] Recommend importlib.abc.Traversable users to implement __fspath__

New submission from Filipe Laíns : The files()/Traversable api is meant to replace ResourceReader api, but it falls short in one dimension, tying the abstraction to a file system path. I propose to document that Traversable users *should* implement __fspath__ if the Traversable represents a
