Mark,
While it might put all the architects here in an uncomfortable position of criticizing superintendents, I think a quick list by each of us about the most typical maintenance changes that do affect our designs might be in order, and informative.
For me, I see so many supers stop cutting the approach to the green as fw. I get it, its probably (always) a budget issue. But, why design a run up approach for strategy or convenient use by lesser players to reach the green only to have it mowed out of the design? This budget shortcut truly changes playability.
Similarly, I see many who eliminate any sort of chipping area cuts because they are too much bother to mow, which reduces design quality, IMHO.
Usually (not always) the first super, who was there at creation keeps the original design intent because you've discussed it with them. But, once they change out, there is no ownership of design that the original super had, and no discussion of why it was that way, and then changes often start happening.
