Yes, and the above is the obvious reason why not. Not that I thought it
was being considered.

Yes, and a byte type isn't needed if the individual bytes are always in
a bytes object. A bytes object with a single byte would be an octet in
that case.

I agree the bytes object shouldn't re implement arithmetic. I would
like bitwise logic operations on bytes() and byte ranges() if possible.
