Meaning any bytes or bytes-subtype will support the Pybuffer protocol, and this should be the first thing we try? Sounds good. For that matter, should the first test be "does this object support Pybuffer" and not worry about it being isinstance(obj, bytes)?

Yes, unless the implementation wants to micro-optimize stuff.

That is a key question. Obviously we have int, float, and complex. We also have Decimal.

The question is also how do you test for them? Decimal is not a core builtin type. Do we need some kind of bformat protocol?
