Excellent idea, but wait, when you get close enough to the icon-less con, how do you work out if it's friendly? You'd spend half your time kill shorting yourself

Point well taken sir, but as Pand pointed out in another post, each aircraft would have wing tips colored to reflect which country they are flying for! Sure I can turn off my Icons, but is the other guy going to turn his off? We both know the answer to that! The problem is, no matter how you fly ACM in here, you are never out of sight of the "other" guys, and they are never out sight to you.
Guess we all have to remember that most of the guys in here are not real pilots, or have never been, so there fore would be lost without that visual reference.
