Thomas,
If anything, I would presume it has gotten "worse" because implements, length and skill have made getting close to the hole a lot easier than 100 years ago.
Colbert was more adamant than most pros I knew. He varied his shot pattern when pins were tucked, and his standard play was to aim from the middle to the high side of the green and curve back to a tucked pin. He always felt the middle should be the safe spot on an approach. When you recall the USGA slope system, even for good players a 10% width and depth area (to length of approach shot) is all they can hit, or 15 x 15 yards for a 150 yards approach. If a center mound divides any but the largest green, the effective target becomes less than that.
So, the good player argument that if they can't hit a target and hold near where they hit (a la, no mounds kicking their shot across the green) it is probably not fair for them, and probably too hard for anyone else.
I had Notah Begay III play in a grand opening where he hit everyone's shot on a short par 3. No matter where he hit his 140 yard wedge, it would spin away from the hole location to a minimum of 10 feet. He didn't think that was good design, or at least pin placement. I have also seen him rant against the little change of grade around a hole location that makes it impossible to chip and get it close to that location, at least from the planned bail out area (in this case, at Dallas National, a fw chipping area right of the green, again where you would expect ams to land. He does understand the concept of certain misses being "death") There, halfway to the hole, a little change of grade from 2% to 4% for about 10 feet just short of the cup, carried chips all the way across the green no matter where you landed it or tried to play.
Lastly, a former design associate put a mound in the middle of the green on a Colbert project. I didn't say anything but knew he wouldn't like it. He dressed down my associate, then said he wanted him as a pro am partner, because "You must be the best damn player in the world if you can hit it close on this green!"
I don't expect this post to change anyone's mind here, but just confirming with Thomas that yes, good players do see architecture in ways that reflect their supreme skill, believing it should be rewarded as close to always as is humanly possible, LOL.
