Jim,
If form follows function, you have to ignore the young bucks and design for who is going to play. There can be some legitimate disagreement about what the average golfer wants to play.
There is Tom's view that all greens should be "interesting". In other words, greens don't always need to be about defense. In fact, even on good courses, what Tom points out in this article is they ought to be designed to reward something more than something else, not defend anything. That is a subtle difference architects from Mac on have understood, but many here don't.
Others believe golf is tough enough for the average golfer, he/she won't really recognize the subtleties you may put in, but score will suffer, etc., to the idea that the green ought to do everything it can to help the golfer hold the green and not three putt to speed up play.
It is really that course dependent, especially in a renovation when you might not have designed a green the way it was originally designed, but its not so tough that you would want to tear it up.
