Watershed moment implies to me that there is a sweeping revelation, and a widespread shift of what constitutes general principles or conventional approaches to issues or ways of doing things.
I think the recognition by those who have the primary influence in the golf course development arena are those that make the money decisions. In that regard, there seems to me to be generally two types of entities. The corporate approach that develops courses as part of large RE and resort complexes, tourist destinations, etc. They still tend to go with the big name player/designers, or the archies that got into the arena 30 years ago and made a splash with the anti-minimalist, move the earth and heavens to create courses of idealistic showy bombastic visuals, to sell, sell, sell the overall projects.
But in my mind, the second kind of developer is the well heeled individual, lover of golf, visionary, who knows what great golf entails, and is keen on putting their name and reputation on creation of a new classic golf course, and those individual wealthy individuals have put in the time and passion to seek out talent, not names. But, those individuals have been in the arena now for several decades. Kohler bridges the gap of corporate big project, looking for big name designer, with his BWR and WS projects, where mininalism isn't even a consideration at all, and the name and talent of Dye was what counted. But, Youngscapp, Keiser, Robertson, O'Neils, and now put C. Johnston on the list, (and the guy who hired Nuzzo) as people that are hiring talent, and boutique design/build. Shockingly, Trump has entered the arena with a change of perception, hiring Gil for Doral.
I think a change is underway, and a recognition as Sully says- that sustainability, environmental care and naturalism is underway with these movers and shakers, both domestically and internationally. But, I see it more as a watershed era than moment. It has already been a process. Tom Doak is getting grey, and Gil is middleaged at best.
Their time isn't a moment, it is already a very mature career of an era, IMHO.
