Not sure if it is mentioned, but I think one reason there is more gca/golfer disconnect is the nature of who actually commissions the gca. I presume in the Golden Age, most work was commissioned by a small dedicated group wanting to get a course built for their own enjoyment, and it set the parameters for the gca work.
Now, with 2/3 or more of all courses commissioned by cities, real estate developers, etc., the owner we serve is also a step removed from the golfer, AND, probably has some other priority than great (or should I say, good "course you could play every day" motives. Those, of course, being selling real estate, winning awards, providing a golf factory, paying down debt, etc. etc. etc. IMHO, the modern process itself separates architect from golfer right from the get go.
