They added a function to the console to enable it because others were using 3rd party tools to do this, and clearly said before that they were banning the use of that mod because it attained the desired effect in a way that could be similarly used for *actual* exploits to the graphics that could potentially give an unfair edge.

But please go ahead and complain more because they added in a feature that many BF3 players desired & were using 3rd party programs previously to attain.
