JVB,
I am seeing less and less completely flat areas even from the likes of Fazio and Nicklaus. In fact, two of the "flatter" courses I've played in 2005 are Seawane and Austin Golf Club, the former faithfully restored to its early 20th century design, the latter by gca.com favorite Ben Crenshaw with Bill Coore. I loved both of these courses, but I would have welcomed some of these lower-scale ground movements.
From the sites I've walked pre-construction here in Texas, I didn't see much of what I would call natural "micro undulations". Perhaps it is the nature of the soil, weather, vegetation, and land use here.
Maybe those in the construction business can inform us on the feasibility and cost of saving and/or creating these features as the land is cleared, grubbed, tilled, and prepared for seeding/sprigging. It would also be interesting to learn about the maintainability of such areas over a long period of time. Perhaps you get bigger bang for the buck with more traditional mounds or bunkers.
Bob,
It is only a problem if you believe that growing the game is important to its survival, and that golf plays a meaningful role in a civilized society. If x number of courses exist in an oversupplied national market and the number of rounds played are declining, then it might give you pause for concern.
Among the reasons for the decline suggested by the research, cost, difficulty of the game, and its time requirements, are typically cited. It seems that placing emphasis on preserving or creating "micro undulations" in fairways would work to exacerbate the problems.
Personally, I've learned to appreciate and even embrace irregularity and quirk since coming on this site. Curiously, my handicap has also increased by more than four strokes during this time and shows no sign of leveling off.
I am now working on adopting a David Schmidt attitude and laughing off my frequent misses. So, perhaps from that standpoint, the more "micro undulations" the more "hit and giggle". I only hope that they come out with a diabetes friendly beer so I can trully enjoy myself.
