The true original course is still pretty much the back nine, that's hardly changed, the original front played differently and gradually got widened. I dont believe the old course ever played to the 6th green in reverse, ie holes 7 and 12 always played over shared ground. With the front nine lesser players should just keep the ball further left, there are not many hazards to trap a tee shot of up to 240 yards from the backs (200 from the fronts) if you keep it left. The holes 2-5 are not crazy blind, there are glimpses. I do not think everything should be a perfect picture infront of you, if we adopted that as an 'architecural rule' it would make many situations difficult, what I would agree with is you need a mix of visible, invisible, tempting and mystery.
