I suppose it could have some strategic value, I'm just not sure how much. I can say I would not be pleased if I crested a hill and found my ball, which I thought should have been sitting ideally in the center of the fairway, in a bunker. It makes the course too dependant on players looking in a yardage book to play the course.
--But as an aside to that, I would bet that Tobacco Road and Tot Hill Farm make a load of money each year from selling yardage books so players can cope with the blind shots, 90 degree fairways, etc.
