Jerry,
I think the game has changed a lot since the Golden Age. Golfers today prefer the faster green speeds that the new grasses, maintenance equipment, and cultural practices provide. With 10'+ greens, steep slops and large internal contouring make getting the ball anywhere close from many angles nearly impossible for most players. Golf is an extremely difficult game for the vast majority. Variety of shots to provide "interest" and challenge is more of a discussion topic among a few of us here than a desire or need among the masses. If I took the average member at my former club to National, Sand Hills, or even Prairie Dunes, he would have little inclination to return. Take him to Colonial in Fort Worth and he automatically knows greatness.
Soft greens along with slow speeds reduces the effect of heavy contouring. I don't really know just how firm the greens were back in Tillie's day, but I think green speeds were more in the 6'-8' range. While I don't think that today's golfer would tolerate that slow speed, I am fairly sure that very firm greens would be rejected, particularly with the frequency of water and sand hazards that frame the modern green.
