>> if isinstance(filename, os.PathLike): By the way, regarding the line of code above, is there a convention regarding whether implementing some protocol/interface requires registering with (or inheriting from) the appropriate ABC for it to work in all situations. IOW, in this case, is it sufficient to implement __fspath__ to make your type pathlike? Is there a conscious trend towards requiring the ABC?
