The stymie rule is great, we just need a small addition that abolishes any penalty strokes for hitting your opponent's ball. That would be a gigantic boon for strategy ;-)
If anything, then this thread has finally coaxed me into reading the Merion article. To me it appears to be fairly well-researched, if a little under-sourced. However, one part which I found to be somewhat of a conjecture is following this quote from Wilson:
Our ideals were high and fortunately we did get a good start in the correct principles of laying out the holes, through the kindness of Messrs. C. B. Macdonald and H. J. Whigham.
I have difficulties understanding this to mean "constructing the holes, i. e. laying them out into the already planned-out ground". Instead, this sounds like golf course architecture to me.
I do buy the stated timetable and the theory that Wilson got started, when there was already a routing established. I don't buy that Wilson considered himself just a constructor and realizer of other men's plans.
