I agree that the digest is meaningless if you're doing progressive
rendering, since you can't calculate it until you have the whole message.
But you can calculate the digest as a trailer if you're doing progressive
production.
Sending the digest as a trailer reduces costs for the sender, whether it's
an upload or download. If the message is small, it's also likely that TLS
is good enough in that case.
