Carl,
As Tom indicated, LENGTH is the critical element, not the architectural features.
An example might help you understand what's happened to these great courses.
The 11th at NGLA is a wonderful double plateau hole with a blind tee shot over a hill down into a swale that ends with a steep berm flanking a road that bisects the hole. For a century, golfers hit driver or 3-wood or utility wood or long iron to ideally position themselves for their approach shot over the berm (usually blind). A prevailing wind is at the golfers back, making it difficult to hold the left and back plateaus when the hole is cut there. The fairway is very wide pre and post road. It slopes down and left, pre, and is relatively flat, post.
Today, long amateurs and pros FLY that road, leaving the lob wedges into that green, a very difficult green to approach from the tee side of the road.
Another example is # 17, a 375 yard down hill, often downwind hole, with an intervening hill/convex bunker complex fronting the green,
Today, long amateurs and Pros are driving that green.
I doubt that CBM contemplated play of that nature.
If I drive my ball 300 it radically changes the play and ability to score on that golf course, since it hasn't been lengthened like Shinnecock,WFW, Merion, Baltusrol, BPB and others.
CBM-SR-CB didn't design their courses with 300+ drives and 150 yard wedges in mind.
Remember too, that the sand wedge and Lob wedge hadn't been invented when they were designing their gems.
