I don't know why they think they are a good idea or were a good idea. Someone dropped the ball in thinking about how the system works anyway. The only time that clutch will come into play is if when the engine is shut off and there is no electromagnetic drag from any risidual flux in the rotor acting on the field. That is the only time it really freewheel. I have heard a couple of people trying to diagnose a bad bearing sound when they shut off the engine and the clutch is what it turned out to be.
