Well, there's two Cape Kidnapper's holes listed, so obviously the list is very up to date time-wise, at least.
I don't recall anyone saying Renaissance has worked on Waterville - does anyone else?
Beyond that, these types of lists tend to be as much controversy-seeking as anything else, as it spurs discussion. There's always people that think they can show how smart they are by being different. Someone wrote a short funny piece in Golf magazine a few years back where he talked about the famous multiple course clubs, and stressed how the truly smart play the other courses - you know, something along the lines of, real golfers prefer Winged Foot East, Merion West, Pinehurst #4, etc.
