Michael,
In about 1970, when first interested in golf and golf architecture, I bought a copy of the then NGF publication "Planning and Building the Golf Course." The idea was still discussed in that book, but more as a cost savings idea whereby a course could carve out bunkers, but add sand later with in house crew to save money.
I actually got into the business in 1977, and only recall a few instances of every using that method, and Killian and Nugent catered to some cash strapped clients back then. I think the practice was on the way out by then. Besides, with the rise of most courses being designed by an architect over a committee, I presume that they presumed that bunker placement should normally be correct.
I mean, we know how far golfers hit the tee shots - yes all over the map but clustered around a few key distances like 300 for pros, 250-260 for good ams, 225 for average players, 175-200 for seniors and good women players, etc. After a few hundred years of architecture, I would be most believe we can predict about where most golfers will play, assuming what tee they use (often a big mistake)
Not to say that downhill, windy, cross slope holes might not yield a few surprises to even the most astute architect, and of course, minor course tweaks still happen almost to every course.
