If the foot slips, the little wheel rotates when it strikes the ground and the arm continues to trail the pedal. Don't think it's too likely to cause a spill like a kickstand could. But it is a lot of extra weight. Maybe with some refinement that design could be used to benefit in cornering or on ice as well.
Maybe it have some merit in commuter biking.
