Just a quick comment:

The supports_instant field seems redundant to me. First, as per your
spec, you can derive it from trusted_instant_providers. And second, why
do you need it at all? Protobuf is designed so it will simply ignore
fields you don't know. So you can just send the instant_* fields in the
Payment message without harm.
