Tom,
I do remember being jarred by fw catch basins every 80 feet at TPC Sawgrass, something I had never seen. I was working with Killian at the time, and had never dealt with a totally flat site not far above sea level.
Like you suggest, I was trained only to grade fairways when they blocked vision (Killian talking) were too cross sloped to hold a shot, or too flat to drain surface water. Even then, he felt basins should be in the rough, not the fw, and tended to add fill, often to crown the fairway, pushing water to basins in the rough.
He was very leary of lowering anything, knowing water goes there and could cause drainage problems, basin or not. Unlike you, he also felt that it was "safer" to raise virtually every green, again to assure that drainage never crossed the green.
I remember one green we cut in a hillside and put a foot or deeper swale behind the backing bunkers to catch overland water. I was there in a big rain one day, and the flow overwhelmed the little swale, washed out the bunker (and since this was during construction, the green mix) while I sat there watching from the truck.
That sort of made me agree with him that it is always better to be safe than sorry, and if in doubt, add a bit of fill and raise the green. Oh yes, and don't underestimate the size of diversion drainage swales! While I have lowered many greens from what he might have over the years to use cut and fill balance on site, I think when I view my work long term, I will find that the greens and green surrounds that hold up best have absolutely the best drainage, regardless of whether they were built artificially.
