Willie — Having written three books on golf architecture, including much about the history of how and why the game developed, strategy and design philosophy, I am not sure why you would think I "need" to regain some insight on old ways of how the game was played. I feel I have a good handle on that, but am always yearning for more insight. That is independent of the question posed.
We must keep in mind that the game is no longer played through the streets of villages, nor is it played among dozens of people all weilding clubs with little regard for protocol. However, those, too, were part of the history of the game.
We no longer play the watery filth, the stymie or much match play*. But those were all a part of the game.
My guess is that you no longer play with wooden implements, but I cannot be sure. I am fairly certain that you no longer play with feathery balls.
None of this is to say that the ground game, width or certain other hallmarks of good courses are out of style — or should they be.

*As a whole, golf is not a game of strokes in a majority of the time.
