I think that's a slippery slope. __bytes__ should mean that the object has a well-known bytes equivalent or encoding, not that its __str__ happens to be pure ASCII. (for example, it would be fine for a HTTP message class to define a __bytes__ method) Also, consider that if e.g. float had a __bytes__ method, then bytes(2.0) would start returning b'2.0', while bytes(2) would still need to return b'\x00\x00'.
