Tom McW: I agree completely and can only add on to your well-taken point of GCA being in its infancy.
Who knows how long life, earth, civilization, society and indeed, Golf, will last and how important any of them will be to future existence? Is Golf halfway to death or only in the first year of its life?
But if we put that aside for a moment, and accept that we can't answer it without error, we can only treat it as living now and forever. The long-dead handed it to us and it seems likely that in some small capacity GCA (the site and the activity) will hand it off to the next batch of the living. And through all the amateur and professional work, thought and critique that are involved in the enterprise and the Game in this vein, a valuable and rewarding quotient comes out - that we get at the truth of something and document how and where and why we arrived at it.
I suppose then my main answer to Mike's original question is, "No. I don't think we're getting into revisionist history nor do I worry about taking the last years too seriously at all."
I think the last post you made Mike, explains perfectly the process of history...how would you know about the 1962 Non-ODG bunkers without previous documentation, how would you know about the fairway contours without sticking a shovel in the ground?
You're correct, in the future people may make all sorts of false assertions about your removal project (just like they made assertions about the ODG's work) but you are documenting the true intent right now and I'm sure you have done so in other forms, including anecdotally.
If Golf goes on at all, I'm sure GCA culture will be apart of it, someone will find it or report it firsthand.
