Adrian, I agree that it's an education to go through the construction process. I've never done it as an architect but as a close and frequent observer have seen two courses take shape, and I see them differently as result of knowing the many constraints (budget, soils, owner's wishes, endangered species, local regs, etc etc).
Yet it doesn't follow that the architect who has had to factor in all of those things has come to the right conclusion and designed the best course possible. The best course he could design, yes. But IMHO architects, with all the resources they can bring to bear, can get carried away, and they easily get to a place where they over-design their work. They build where they don't need to, put in a nest of bunkers where one well-placed bunker would do, get too clever with their green designs, and on and on.
Maybe I'm guilty of "group-think," but I believe that Bill Coore said a mouthful when he said, "If I tried to imitate nature, it would only showcase my futility." Architects are famous for their desire to control everything, but I think CC try to practice humility in their work -- they acknowledge their limits. They know when to leave well enough alone. About certain things they are absolute perfectionists, as I know from having watched the building of Bandon Trails. About others, they are hands off. Instead of flattening a ridge, they figure out how to build the hole around it.
In any case, I think many contemporary architects can be faulted for practicing over-design. They come to their work with many assumptions about design and impose these assumptions on the courses they build. The result is often a golf course that feels contrived, and that dates quickly.
