Maybe for Realistic mod. Don't see why you'd need it in Normal.
Nothing against nosejj, butThis, my friends, is mindless and dumb. This a change of general movement and controls (i.e how you make your Soldat move), it shouldn't be dependent on which mode you're playing. You don't have different movesets for those two, even though there are different tactics involved. I don't see why realistic mode should have it, but not normal. Why dump useless/bad things and ideas to R-players anyway?
In general, I don't see any harm at this, but I won't jump to conclusions. I have already lost touch to Soldat controls D:.
