I feel their pain!
I generally live by the axiom of "you can't fool mother nature" when it comes to sunlight and air movement in particular. I come to that conclusion having built on the perfect green site enough times, and having been around long enough to witness some less than perfect results anyway, owing to agronomic conditions.
In general, fans, sub air systems and the like are like life support systems, and only improve conditions at most 5% in bad situations. And that often isn't enough to make a long term difference. Clearing trees for sun and air movement, placing greens anywhere but deep valleys, etc. does a much better job of providing growing conditions.
I am not sure if gca's don't consider maintenance aspects more or less than they used to. I suspect most are like me in that as time goes on, they pay more attention to it, based on unpleasant experience. In fact, I would almost say that if they don't, it shows a lack of experience, to the degree that I would say that they aren't golf course architects - they are just playing in the dirt!
That said, I know that there are always situations that seem to require it, especially when routing housing courses which tend to follow the valleys.
BTW, I have a situation now where I left a fw ungraded, so didnt' plan to add topsoil and now that grassing has begun, its painfully obvious that the fw is short of topsoil and some should be added. However, its near the project end and the owners rep doesn't want to spring for a few thousand $ for it, despite me telling him he will regret it. So, even with experience, certain bad agronomic conditions creep into the project for reasons beyond the gca control.
And, I have never heard a superintendent say he has enough topsoil. Consulting at a project recently, where I know the topsoil was put down as fully as possible, the super says he doesn't have enough, and may be right. I think its time to go from the "standard" 6" topsoil depth to 8-9" when stripping and replacing.
