I think the current behaviour is fine, in that the alternatives are not better at all. In the absence of a type inherently "superior" to the others (as float can be to int, except for very large integers :-)), it makes sense to keep the type of the left-hand argument.

Note that .join() has a slightly different behaviour:

>>> b"".join([bytearray(), b""])
b''
>>> bytearray().join([bytearray(), b""])
bytearray(b'')
>>> b"".join([bytearray(), memoryview(b"")])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: sequence item 1: expected bytes, memoryview found
