And this is exactly about the routing.

The three fields that today should be part of the envelope is
"Host:", URI (Sans query part) and Session-Nonce.  (Since we don't
actually have a session-nonce, today people route on cookies.)

And like all other message transfer systems from snail-mail and
forward, the envelope need not give anything away, because what you
put on it only have to get the message to the right place, it doesn't
have to _be_ the message.

Never attribute to malice what can adequately be explained by incompetence.
