They actually put it there for three reasons: when you are stopping/starting, downshifts, and low rpm upshifts. A clutchless upshift when you roll off the throttle isn't any different than using a quick shifter that briefly cuts spark to unload the transmission while you shift. BMW, Ducati, and Aprilia all have bikes available that come from the factory with quick shifters for clutchless upshifts. With factory warranties. Their transmissions are built the same as the Honda.
