When passing an object that is of type str and has a __fspath__

However, when passing something of type bytes, the second approach

Is this intentional? I think a __fspath__ attribute should always be
preferred.
Yes, it is intentional. The second approach assumes __fspath__ can
only contain str, so there is no point in checking it for bytes.
Either I haven't understood your answer, or you haven't understood my
question. I'm concerned about this case:
class Special(bytes):
def __fspath__(self):
return 'str-val'
obj = Special('bytes-val', 'utf8')
path_obj = fspath(obj, allow_bytes=True)
With #2, path_obj == 'bytes-val'. With #3, path_obj == 'str-val'.
I misunderstood your question. That is... an interesting case. ;)
