Python 2.x was different, as the automatic unicode coercion meant
class developers still only needed to provide __str__ (or __unicode__
if they wanted to return non-ASCII data).
__bformat__ (and similar ideas) are somewhat different beasts due to
the encoding issues involved. Those aren't insurmountable, but they're
things that don't come up with pure unicode handling (2.x unicode, 3.x
str) or data that is essentially assumed to be latin-1 encoded in many
cases (2.x str)

I'm still not sure about that, since the 2.x str.format() pretty much
ignores the associated encoding problems, and I don't believe
perpetuating that behaviour would be appropriate for 3.x bytes.
