Is there a way to return damage to attacker, similar to server.pve true? It would be awesome if you could add this as an option to extend existing rulsets logic by adding "hurt themselves" to existing "can hurt" and "cannot hurt".
Something like:

players hurt themselves players
players hurt themselves dispensers
players hurt themselves traps

Or any other way to implement this option would be very cool. There are some players on PVE servers, that like to shoot everyone all the time and even though they do no damage, sometimes it would be really annoying. And if you are not admin you just can't do nothing to prevent them from this.
