No they don't, your "weight" of certain point of view is questionable as for any other individual, look at the big picture. Fact is, simple poll would explain a lot and out-weight cons, if it is fun and enjoyable for the player. Few loud individuals can share a voice, but they don't represent some solid numbers, do players have made consensus about whether they want it in game or not and again, those "cons" were pretty absurd, questionable, allow me to add that again.
Realism, player interaction, "proper" recognition or at least those miserable and failed attempts to assume what is right or wrong, boring and fun, or how the player should interact with others more than to just shoot by color is completely irrelevant, there is much more than color to recognize and that certainly is not the issue witch was presented in those wall of texts that lead into totally obsolete display of incorrect information, currently there is some gray color everyone shoots anyway, might be blue or violet, yellow, though that cannot be an argument against it. I don't see reason to prevent that feature.
Bring back old NC.
