If you read that article, Tillie ended up recommending taking out some of his own bunkers, too.
I have been called back to many of my courses since the great recession to reduce bunkering. Some find it awkward, but my take is its a sign of the times, and would prefer to do it over someone else. It realigned my philosophy a bit. In reality, my courses with 50-60K SF of bunkers don't play any worse than those with 90-100K SF. In fact, even visually, I now find that much bunkering a bit much in most cases. You have to get creative with alternate hazards, like grass bunkers, mounds, chipping areas, etc.
Or, as some other architect said (not sure why I can't recall who it was....) the green should always be the main visual target, bunkers secondary. That alone explained why I don't care for a number of Maxwell courses - all you see on the approach are big yawning bunkers in many cases. I reserve that for one hole a round, usually a par 5 or short par 4, hoping one example is memorable.
To answer the overall question, yes he was right, and he set the tone for architecture right up until the free spending days of the 90's......When money flows - usually about one decade out of 7, people forget the basics.
I started in 1977, I tried on occasion to get in some foreground bunkers, and especially bunkers 20-40 yards in front of greens, just because they looked good, and old fashioned. Inevitably, the question (that led to their demise) was, "Why build a bunker that doesn't come into play for better players?" The implication was they slowed play, punished golfers who had already punished themselves by coming up short, etc.
If architecture balances playability against aesthetics, its hard to justify a lot of bunkers in non traditional landing zones. If a duffer has mis hit his tee shot, and is more than 200 yards (or his maximum second shot distance) what good does it do to punish him even more than the bogey he must likely face?
Given the extra cost of building and maintaining bunkers these day, he was not only right, but now is more right than ever.
