Those architects all understood the need for flexibility. Flexibility is/was most easily accomplished by moving tees. They were very wise and quite right.
I think one can argue for both finality and flexibility--as MacKeznie did.
They all seemed to foresee the dangers of uncontrolled advancements in the golf ball--Macdonald and MacKenzie both advocated the floater (a lighter ball that didn't travel as far).
I've not read any architect warn about the speeds of greens getting out if hand. I don't believe they ever dreamt greens could be brought to speeds found today. Super fast green speed are a popular means of challenging golfers today due to the unreal distances the ball is traveling. One wonders what MacKenzie's reaction would be to his greens being described as freakish once again.
Darwin, who lived longer and wrote more than any of the others, was an outspoken critic of altering prominant designs.
Here are a couple exerpts from MacKenzie and Behr:
"If a course ever has to be altered, it means that the architect was wrong in the first instance, and yet one sees all over the world golf course which are being continually altered, and not infrequently the changes that are made are no great improvement on the old holes.
It is often suggested that changes in the ball may necessitate alterations to the course, but this is nonsense. A well-designed golf course should suit any golf ball or any class of player. The Old Course at St.Andrews is classical example. It was the best in the days of the fether, guttie, and the Haskel ball, and Bobby Jones still describes it as the best.
There are many golf architects who have never has a golf course altered when they have been given a free hand to carry out their ideas in the first place. I do not think that Jf Abercromby, Harry Colt, or Max Behr have ever had a course altered.
None of our courses in America have been changed,.."
~~ Alister MacKenzie circa 1930
"Perhaps, it is not right to so castigate the penologist, for to be restricted in designing holes to fairways of limited width is a great handicap for strategy to surmount. This is especially true in that freedom, demanded by a sport, loses all sense when subject to obvious restraint. Consequently, golf architecture, in an effort to police the thieving of space by the present ball, has turned inward upon itself in an effort to tell the golfer what is right and wrong, whereas it is imperatve in any sport that the pursuer of it is the sole judge. Because the ball as implement is dishonorable to a sportsman in making him take advantage of a hole's sole live defense, the sport has verily lost its soul. And such is the condition of golf as it is played today."
~~Max Behr 1952
