Specifying the service interface a protocol provides (and what it requires from
other protocols) is often very useful. And is something we have done in many

In some cases, there is a surprising benefit:
It makes a clear distinction between what is "internal" to the protocol,
versus what is payload that is delivered to the consumer (next layer up or
receiving application.)
Sometimes, the way a protocol is specified does not make this distinction
completely clear.
