yeah i do this, it breaks the fall when you drop of a ledge, you can literally float to the floor if you hold it, I don't use it to great advantage , it just makes it quicker to get to certain places on the map. i like to duel quickly so people dont have to wait.
I also got called a hacker for doing this, wtf? I couldnt hack my way into a bag of crisps for christ's sake, hehe
Incidentally you don't need ant force jump to do it it happens regardless.
