Niall,
If part of the mission of the architect is to provide a disinterested challenge for all level of golfers, shouldn't one of those challenges be a test that requires the planning and execution of three consecutive shots ?
What's lost in your premise is the abandonment of having the architectural features interface with the golfer, on the drive, second and approach because with today's modern golfer, the features intended for the DZ are often ignored by the golfer's ability to fly it over them without much concern for consequences.
That then removes the sequence of challenges on the second and approach shots.
Recently, I was playing at Ridgewood, (NJ) and couldn't help but marvel how wonderful the par 5's that AWT crafted, had remained relevant, even though some of the tees remained stationary over the intervening years.
Holes like # 3 East, # 2 center, # 4 center, # 4 West and # 8 west are wonderful par 5's for 99 % of golfers.
For the other 1 %, # 4 West can be lengthened to 600+ yards and remain relevant, the others tend to be landlocked and for PGA tournament purposes have had the tees moved up and had the holes converted to par 4's.
If they had the land, I'd rather see the holes lengthened, such that the architectural features and their juxtaposition returned them to their intended mission, interfacing with the golfer.
Unfortunately, distance and high tech have prevented that from happening.
But, for the other 99 %, I'll let you play the par 5's at Ridgewood and bet you on par all day long.
