I guess a stateful proxy would only need stateless forwarding only in the first few minutes of operation (because of timer C) - after that it should have all the transactions. Not sure we can or want to ban stateless proxies though. Isn't this "recovery mode" simply the same as saying that for the first few minutes the stateful proxy acts as both stateful and stateless proxy?
