Jordan,
You have to remember, every April, It's "Show Time"
This is a MADE for TV event.
The colors, the contrasts, the flowers, the mowing patterns, and then, The Tournament.
ANGC has taken on a life that extends far beyond the architecture.
ANGC and The Masters have become Icons of American golf.
Admired and emulated by most.
Hence, IF ANGC decided to swing back to more natural looking bunker edges, I think you'd see that style copied across America within a very short time.
Tommy Naccarato posted some black and white pictures of Friar's Head and I must say that the black and white contrast brings a unique quality to pictures of golf courses, especially ones with an abundance of sand.
If the picture of # 10 was colorized, I don't think you'd be as enthusiastic about the look.
Downstairs in the Balusrol Clubhouse, I think there's a neat photo of Trevino playing from behind the 4th green at Baltusrol during the Open in 1967. In that photo the bunker edges have long grass, certainly not a manicured look.
The shaggy look.
Somehow, over the years, that look went to the manicured look.
I like the challenge presented by the shaggy look.
So, while I agree with your desire to see that look returned, I don't think it will happen until a club hosting a Major Tournament has that look.
That's one of the reasons that I was bitterly disappointed that Merion and not NGLA got the Walker Cup.
Merion's had plenty of air time, but, exposing NGLA to the golfing audience might have had a far more beneficial effect, architecturally, maintainance wise and perhaps, looks wise, on American golf.
