 The manual mentions technical terms (including rendezvous circuits)
 several times already, with no ill effects so far.

 >What that entails for the user to set it or not? Should we mention that
 it's primarly there to make port scanning harder on the attacker side
 (which is it really?)
 Describing it in those terms encourages users to place their trust in
 2^16^ security through obscure ports, and ignores the already existing
 solution: HS client authorization.

 The only thing I would change about this patch is I think it should be set
 to `1` by default.
