But formatb() feels absurd to me. PEP 460 has neither a precise specification or any actual examples, so I can't tell whether the intention is that the format string can only contain {...} sequences or whether it can also contain "regular" characters. Translating to formatb(), my question comes down to the legality of the following example: b'Hello, {}'.formatb(name) # Where name is some bytes object

Yes, it's allowed. But so is:

b'\xff\x00{}\x85{}'.formatb(payload, trailer)

The ASCII bias is because of the bytes literal notation.
