Fascinating question, Ally. I'd imagine that, in retrospect, any 'current' generation/era tends to see previous ones as more static and less dynamic than they actually were. Besides the ones you've mentioned, I think of some of the first golf-focused planned communities/housing estates in England (eg St George Hill) as 'modern'; and I think of CBM at NGLA as modern, and so too the early Pete Dye-Jack Nicklaus collaborations; and I think a case can be made as well for Sand Hills, and for all the work in China, and for Mike Keiser's retail golfer concept as all being then-modern phenomena.
