if you put it on the standard generic zoner ID, you'll have trolls going round zoner bases (most likely in caps) and baiting zoner players into shooting them, thus giving reason to shoot back.
There's a reason why zoner diplomacy is still routed through the officials. Same principle here. by giving it to officials only, there'll be very little chance of troll baiting to get zoners to pews.
plus, you know, official factions need something as a bit of a exclusive drawcard over indies. This just happens to be the zoner version.
