I would say that realy it's a non-issue for playing with other people as has been said befor in this thread, real peopl should call out if they're crossing your line of fire or peel behind you. So realy this kind of "feature" is a short cut to stopping problems with AI, why not look at the reasons you want this kind of thing to begin with. Rather than asking for such a short cut to begin with that is realy the start of a slipery slope.
