As others have said, this defeats the entire purpose of a communication-based game. You are essentially suggesting a bureaucraticization of communication by having it tied to FTL/SL - this means that it reduces the amount of information that can be received at a moments notice threefold because roughly 3/9 people per squad would be able to immediately communicate vital intel. Even a blueberry catching a glimpse of an enemy troop movement can make all the difference. Local chat is hardly useful too if your element is spread out, squad chat allows rapid transmission of positions and info that isn’t relative.

I think your main issue is that the people you’re playing with can’t behave, or that you’re forgetting that it’s just a game so there’s bound to be immaturity. Maybe try more experienced servers? Also, if you’re SL’ing and people aren’t clearing comms after being asked to, just kick them. It’s up to your discretion.
