Exit relays dedicated to onion only traffic
Allowing exit relay operators to set up their exit node to only allow onion traffic and not allow access to the surface net could drastically increase the amount of available exit nodes. It would drastically reduce the risk from running one of these onion exit nodes because all the traffic is encrypted at all times and no malicious traffic would come out of the onion only exit node. This could also make it much safer for people in oppressive countries to host these nodes with reduced risk. If this would be implemented in a much larger amount of exit notes would come online, this could possibly increase anonymity by makeing it much harder for a attacker to compromise a large percentage of the exit nodes because of the larger number of exit nodes.
