I really am interested in the statistical "revolution" within golf, as I (like probably anyone else who has ever played the game) fully agree that the standard stats are even less useful than RBIs are in baseball.
That said, I don't love the idea of it being used as a factor in course design. I suppose there are any variety of ways the data could be used by a creative thinker, but my fear is that the easiest application is to say, "These three holes on Tour Course XX are significantly easier than average and should be toughed up by making the fairway harder to hit/green smaller/etc." Which is a concept I dread.
