I agree with Forsaken1111. The opponent AIs should not be offended/threatened by armed private/civilllian ships. I'm very much against many types of artificial limitations. We can not even control such ships.
Military ships of certain small numbers should not offend/threaten them either if the destination is a refueling station that is protected.
