Not as absurd as you might think. The problem with platform pedals is keeping the shoe stable on the platform, but I've ridden with a broken Speedplay spring so the shoe was fixed in the plane of the pedal but there was no retention normal to it. Except at very high cadences, there was no noticeable effect.
