True. But each part/member is, and if the sender sends a single member
it can be sure that the recipient can tell if the message got truncated
even if there is no other forms of delimiting. It's the sender that
selects to send the message without any other form of delimiting.

And in this case the protocol do not really depend on the delimiting
being detected proper. The message delimiting is the same as identity
encoding without content-length, by closing the connection. But unlike
identity encoding the recipient can clearly tell if the message got
unexpectedly truncated, with the small exception of a sender sending
multiple gzip members in the same stream and the message getting
truncated exactly between two members.
