That's different. PEP 461 excluded them because it was talking about
bytes.format(). bytes.__format__() would be much easier to deal with,
because its result must be unicode (str in 3.x).

I don't think just adding bytes/bytearray.__format__() per se requires a
PEP. It's not a very radical addition, similar to datetime.__format__().
But I wouldn't be opposed to a PEP to decide on the specifics of the
mini-language that bytes.__format__() supports.
