This. Flicking is probably the most egregious offender. Not only is it not useful in an actual duel (not that that's particularly practical anyways.) But it also depends on properties of the modern epee/foil (extreme flexion.)

Btw, the way to counter a flick is to not get hit by it. I know that sounds stupid, but whipping the blade substantially decreases it's length. So just space around it.
