Where would we be, if we all followed the manufacturers warnings?
Good think Chuck Yeager didn't follow the Norm, would we all have Wright Fliers. Or would we even have the the Wright Flier?

The U Can Do as with all 3D/Unlimited aerobatic class aircraft,push the edge of the envelope. And how would we know what the edge was unless someone was always pushing it?

I think we are all learning from each other here.
