That is the rational given for every redesign of a significant old course. Ken Killian, Rees Jones, Tom Fazio, Ted Robinson, Martin Hawtree, etc have all said the same thing. If the design is unique, it should be preserved and protected IMO. North Shore was a unique design, due to the impact of CBM, Raynor and White. It had some of the boldest greens those gents ever created and it featured free form bunkering, which was unusual for CBM & Raynor.
