    Prop327: Onion service rate limiting is not congestion control.
    
    It is just rate limiting. We could apply real Prop324 congestion control to
    the intro circuit, but so far we have not done so.

   So far our attempts at limiting the impact of introduction flooding DoS
   attacks on onion services has been focused on horizontal scaling with
-  Onionbalance, optimizing the CPU usage of Tor and applying congestion control
-  using rate limiting. While these measures move the goalpost forward, a core
-  problem with onion service DoS is that building rendezvous circuits is a
-  costly procedure both for the service and for the network. For more
-  information on the limitations of rate-limiting when defending against DDoS,

   If we ever hope to have truly reachable global onion services, we need to
   make it harder for attackers to overload the service with introduction
