Testing has shown them it just does not work to any advantage and is actually detrimental. Clipless basically keep your feet in one desired position, and that is a benefit in various situations.
FWIW, for roadies I would say its absolutely a question about effectiveness. And its rather simple: to pull up at the same time as you push down enables the rider to use both legs at the same time. Less fatigue on both legs actually. FWIW, I never met any serious rides with a different opinion on that subject. Keeping your feet in one place? Then you need nothing at all I would say...except pedals.
