Supporting this last one is PEP 461. There are no proposals on the
cards to add a b"...".format() method (it's not out of the question,
but there are problems to be overcome because of the extreme
generality of it), yet we have percent formatting for bytestrings. I
think that's a strong indication that percent formatting is fully
supported and will be for the future.
