Yes, no, sometimes, always, never, maybe.... Platform and condition specific. F18's are generally pretty durable and forgiving to rotation while some boats have to think "protect the mast" all the time (i.e. On F18's in light and middle conditions, you can adjust for flow). I'd argue that for most people if letting the rotation out is going to damage transitions, the speed lost to not working it is less than what would be lost in poor boat handling (pound wise, penny foolish).
