The whole point of DQs, to the best of my knowledge, is to stop athletes from gaining an unfair advantage. I'm almost certain that nobody suggested, when rules were being proposed, that this'll be great because not only can we disqualify cheaters, but now we'll also be able to disqualify people for doing harmless, accidental things that had absolutely no effect on the outcome of the competition, just to stir up bad feelings and annoy people. But here we are.
