Following up, I think this leaves us with 3 choices:
1. Do not implement bytes.format(). We tell any 2.x code that's written
to use str.format() to switch to %-formatting for their common code base.
2. Add the simplistic version of bytes.format() that I describe above,
restricted to accepting bytes, int, and float (and no subclasses). Some
2.x code will work, some will need to change to %-formatting.
3. Add bytes.format() and the __format_ascii__ protocol. We might want
to also add a format_ascii() builtin, to match __format__ and format().
This would require the least change to 2.x code that uses str.format()
and wants to move to bytes.format(), but would require some work on the
3.x side.
I'd advocate 1 or 2.
Nice summary.
I'd advocate 1 or 3.
