In baseball, you can throw a spitball. Its cheating but you can get away with it. In golf, you can use clubs that aren't to spec allowing you to hit it further or you can use an adjustable club giving you an illegal advantage. In NASCAR, the rules specify the setup for the car such that each is car in a race is almost identical and thus it should be the driver's skill that decides who wins the race. Again, there is nothing preventing you from actually using mods or cheats in outdoor sports or online during casual play. I think this mod for COD is cheating. The weapons we have available are designed to give balance to the game so that no one setup is so overpowering over the other. You have a sniper that can kill me with a single shot, yet a slow rate of fire. Well, I have an m60 that has a fire high rate of fire but I need 20 hits to kill you. Its balanced, and thus the players skill should ultimately decide who wins. Its not to say that there aren't some things we can do to gain an advantage. A high performance pc, or a high accuracy mouse I think are all legal in the same way that a player might choose his bat type, glove, or golf ball. Just ask yourself. In the real world, would I be able to make this sniper rifle fire on auto-mode? And isn't COD4 supposed to emulate real life?
