David,
To respond to many of your points:
I completely agree that the shot values in 2013 will be much different than in 1930, but the problems to be solved on each hole will be, for the most part, much the same.
The shot values HAVE to be different because the conditions and equipment - ESPECIALLY the 1.62" ball - have completely changed. However, most of the greens are near-identical albeit much faster.
As I have commiserated with Pat Mucci, pushing back equipment is no more likely to happen than returning greens to their originally intended "stimp".
There isn't MUCH room to expand the great old courses, but it can be done. Merion and Shinnecock are the two with which I am most familiar, but Baltusrol, Winged Foot, Bethpage and Olympic seem to have also found the necessary real estate. It can get in the way of gallery flow, so it isn't ideal, but it seems to work.
The great old courses can only play the way they were originally intended if:
1) fairway watering systems are removed;
2) the 1.62" ball comes back;
3) any wedges with "bounce" are declared non-conforming;
4) green speeds are limited to whatever was possible "in the day" (6?, 7??, 8 max???).
Since those will likely never happen, it's too late and it has been too late starting in about 1931 when the 1.68" ball became mandatory. I think Sarazen's sand wedge was a mid-30's invention, etc. etc.
I agree that the best players no longer "fit" the best old courses FROM THE ORIGINAL CHAMPIONSHIP TEE BOXES. Shinnecock has done fine with "Open tees", Olympic has done fine and so will Merion.
You say "force fit" and I say "adapt when it's inevitable and necessary". That's why there's chocolate and vanilla ice cream.
I happen to believe that the routings, green complexes and pure golf architecture of the Golden Era courses are too memorable to be discarded without every conceivable effort to keep them do-able for national championships. In my opinion, it hasn't always been perfectly executed the first time (e.g. Bethpage), but the results do seem to be markedly better after the maiden voyage (e.g. Bethpage).
Since I think I understand that you disagree with the above, do you have any suggestions for courses where U.S. Opens, etc. SHOULD be played? Or haven't those courses been built, as yet? That is not a snide remark, but a truly serious question. If not Merion, Olympic, Shinnecock, Oakmont, etc. - then, where??
