Interactive environments would be hard to do. I don't think the cod engine could handle it. Anyways It would be annoying in MP. Kiddies blowing up all the buildings on the map.

Button combos and "triggered events" like leaning when near a wall would clutter up the game. Everything needs a separate key to work off of or you will accidentally trigger the wrong thing sometimes resulting in your death. Which is the worst way to die.

Oh and leaning is one more thing that the PC version has and poor console kiddies don't.
