 sure how to proceed code wise because what I've tried with `SendMe=1` and
 it was not working. Basically, what I need is a confirmation that what is
 proposed makes sense and is doable that way. If so, I'll push the commit
 that implements this and will ask nickm to hunt down why it is failing.

 SENDMEs are part of circuits and streams, so we could increment the Relay
 protocol version:

 {{{
 9.3. "Relay"

    The "relay" protocols are those used to handle CREATE/CREATE2
    cells, and those that handle the various RELAY cell types received
    after a CREATE/CREATE2 cell.  (Except, relay cells used to manage
    introduction and rendezvous points are managed with the "HSIntro"
    and "HSRend" protocols respectively.)
 }}}
