Except it totally exists in BW ubers. Also when using quick stall the point is you're stalling with offensively oriented pokemon. When I say that I don't mean offensive monsters like salamence that run those completely wasteful defensive sets, I mean pokemon that would often be seen as sweepers/all out attackers/utility counters which retain their power but use their speed to harass the opponent at the same time. Subdisable gengar is a perfect example, despite being powerful and dealing decent blows with it's attacks it can easily harass opponents with it's speedy substitute, especially with t spikes.
