Good insight, Eric
Golf course are and always have been, in fact, like palimpsests. The land was the papyrus and the design efforts of the various owners of the land the periodic "writings". Many great courses, including Shinnecock, Dornoch, Merion, TOC, Pinehurst, etc. evolved this way. It was only until some people began to read into one or more of the most recent "writings" on some courses some sort of esthetetic (form) value over and above the playability (function) of the design that the act of "writing over" the current design became an issue.
People seem to want to "preserve" a few particular "palimpsests" as they are, or they imagine they were, based often on crumbling sepia drawings from some point in time when none of us were alive and/or cognizant of eithe the form or function of a proper golf course.
And yet, the writings on those palimpsests (i.e. "Golden Age" designs) are just recordings of what was, and was appropriate, for those bygone days. They have historical value (just as the inventories of Upper Nile farmers written on real palimpsests have similar value). Do they have functional value these day?
Sure they do. To people like the 99.9% of the people on this site who can only carry their drives up to 270-280 yards or so, and are happy to get within 25 feet from a sidehill lie 120 yards from the pin.
However, we are like clever college students who can read "A Portrait of the Artist as a Young Man" and enjoy it, and can even wade into "Finnegan's Wake" without drowning, even if we only comprehend bits and pieces of the work, from time to time. On the other hand, the experts at this sport in which we dabble, the touring pros, slide through "A Portrait...." (i..e Dornoch, Cypress, etc. on a normal "members" day) like a knife through butter, and they tackle "Finnegan..." (i.e. Shinnecock, Muirfield, etc. set up for a proper examination) with a knowledge and skill and art that we wil never really understand.
I think it is selfish to try to tell the owners of ANGC or NGLA or Dornoch or TOC or wherever that they cannot write over their "palimpsest" just because some small band of esthetes, who have very little practical idea as to the higher challenges which might be created from such a revision, want to preserve the field of play for their own limited abilities and/or as an historic artefact. Of course, they, you?, have that right.
