You have control over your own fire. You don't control that of other people. You would have to treat any unknown 'friendly as an enemy'.
Everybody can shoot down your B-29 or 262 on the final for lulz. Or because they 'know' your a spy.
Is the mayhem worth it?
point being, the poacher is taking advantage of the fact that he will suffer no consequences. You say I do not have to shoot, you negate the fact that the poacher is entering the active bullet stream, at which point there is only 1 consequence, you pay the price.
As far as the mayhem, abso=fuccccing-lutely. Peeps have fallen into patterns, WAR is mayhem, this will strengthen squads and create the next level of game play. And if a snot nose decides to act the child, then he can suffer some of his own style of play. Squad retribution..................
Personally, if hitech would let me, I'd make a map where its no holds barred, and capturing bases got you use of aircraft, but that's me...............
