Mark S:
Yes, there are probably more wild greens on modern courses than those that remain on classic courses. And hopefully we haven't been wrong to build them all.
The one difference I would note is the SIZE of those wild greens. Crystal Downs and White Bear Yacht Club are two of the wildest sets of greens mentioned, and between them I think there's only one green that is over 6000 square feet. To me, it's almost mind-blowing that they could pack so much contour into such a small area ... but of course they weren't thinking about 3% maximum pin positions and green speeds of 10 or more.
The more I've worried about such things, the bigger my greens have gotten, to allow for all the contour. But, bigger is not better, when it comes to the cost of maintaining a golf course. So, one of these days I may build a course with smaller and flatter greens. Somewhere.
P.S. to Steve: If they go to Lederach to see wild greens, they should go to Stonewall (North), too.
