Seems to me this is an easy call.
Before, the 5th hole at Chambers Bay was a very simple, elegant design, a long, wide par 4 with a Lion's Mouth bunker, and a clever green design to augment the bunker. On this hole, right hand pin positions are best attacked from the right side, and vice versa. Since the hole is long, distance off the tee is also rewarded. For me, the hole was plenty difficult as was.
By placing bunkers in the landing zone, the hole becomes more difficult, more expensive to maintain and less strategically interesting.
Patrick, since nobody mentioned an example of a hole where the center of the fairway is not ideal, #10 at Riviera is a good example.
