I don't want to manage a "business relationship" with every shop I buy something from. That's way too much effort. There can certainly be cases where a more complicated relationship is created by bootstrapping off BIP70, perhaps with an extension, but nailing the ordinary buyer-to-seller relationship seems like a good scope for BIP70 for now.
