The problem with trying to solve the following issue: "a bytes instance from python3 is pickled as custom class in protocols <3" is that if we pickle bytes from Python 3 as a 2.x str in protocol <= 2, unpickling it using Python 3 will yield a str (unicode), not a bytes object. Therefore the whole chain (pickling then unpickling) will not be idempotent.
