GJ,
You could win the "black and white thinking award" for your post 17. Just because the architects arrange the holes for visibility as much as they can, doesn't mean it can only be done on the worst sites ever (i.e., Iowa cornfields....actually, courses I have worked on in NB and Iowa have GREAT rolling golf land, rarely a flat lie, but not so hilly that its a goat climber.....so even your presumption of bad sites is way off.) That one could get you on my "Bite Me" thread, only because I hear so many either or one off examples on this site justifying whatever.
Suffice to say, Ross, Mac, CBM and others preached the mantra of visibility, and especially visibility on approach shots to plan the strategies they were trying to implement. My take is the accepted blindness more than, say Fazio, because they didn't have the earthmoving capability to do it every time, in every situation, whereas modern architects do.
I will agree with the statement that only a few golfers can used the base of pin visibility greatly, although I do like (as a golfer) to see the base of the pin to know how far from the edge it is, which might affect even MY strategy. However, never really thought of it until I heard JN or other pros in design tout its virtue. Since then, I try to do it, but don't really obsess over it either. In general, its better if you can do it, but on probably 3-9 holes, it just isn't possible (usually, the uphill ones) Even then, I try to push the bunkers to the outside edges of the green if visibility is possible, and they would block it. I just prefer aiming at the green as a target, rather than aiming between bunkers to a flag. Maybe not everyone does.
To answer your question, I don't really design for tour pros. On the other hand, the best golfers seem to mimic what they say, including base of pin visibility, and they can generate buzz and become tastemakers. If good players give your course a bad review (or raters trained to look at such things) even average golfers can tend to not like it, even if they don't really understand why.
Hate to accuse golfers of a sheep mentality, but I have seen it. Eventually, golfers of all levels will find courses they like best and suit their games, but in the instant marketing world of golf, at least pre-recession, it was hard to convince owners to build a course that golfers would "eventually" grow to love.
