To ignore the influence of the Arts & Crafts movement on all manner of late Victorian and early Edwardian life is to ignore history. If you prefer to look at golf architectural history in a vacuum, that is you perogative. I prefer to analyze it within the context of overall societial conditions.
Everything you wrote about Park is correct, he was a major figure in turning the tide. But he wasn't the only one. You must also give credit to Hutchinson, Low, Paton, Mure Ferguson, Fowler, Hutchings and Colt, among others.
The other reality you seem to ignore, the epicenter of the A&C movement was London, actually the countryside on the outskirts of London. The exacty some place that Park, Hutchinson, Fowler, Colt, Mure Ferguson and company were doing their thing. (And the same place Voysey, Jekyll, Lutyens, Morris, etc were doing their things).
If you study their writings, all these diverse people, you will see the same themes and philosphies coming up over and over, no matter the art or the craft--its difficult to ignore (for me anyway).
