Horrible suggestion.
You cannot honestly argue for this while still having 3rd person as the dominant view.
Think about this.. you cant turn your head without turning your body if you disable ~, and that is really stupid... So if you want to go the realism route with your argument you can consider that... but most folk are probably pretty weak in terms of logic and will simply say "well you cant turn your head around 360 degrees like ~ allows you to..
i think ~ is good... it helps "make up" for the lack of things like crouching, or other stealthy ways to look around..
