I hate to re-stir the pot regarding the work of the post Doak/CC/Hanse generation, however you want to term that bunch, but I do feel that, increasingly, especially with the real up-an-coming firms, hubris tends to get conflated with intent. In other words, that these restorations are vehicles of self-promotion for the restoring architect, to further their own careers and to show off of their own skills on the dozer, far more than to actually emphasize the work of the original architect. If time is, in fact, a flat circle, then we're creeping back to the ethos of the renovators of the 1950s, 60s, 70s, and 80s again, in the same way that superfluous, inconsequential shaping is back in their original work.
By and large, the market drives the demand. The fact that there have been so many renovations and restorations of late means that works instantly need to catch the eye so as to not get lost in the shuffle, in combination with what is becoming an oversaturated market full of younger firms looking, and needing, to prove themselves. Moreover, most raters tend to visit once, often during trips consisting of numerous visits to different clubs, and then submit their ballots right away. As such, in order to stand out, particularly at lesser-known clubs looking to get a major jump in status and rankings from a renovation, boundaries keep getting pushed and pushed and pushed, work becomes increasingly heavy handed, thus moving increasingly from what was there - the original features - to "intent" - "intent", once again, that is far more the renovator's than the original architect's.
The nature of social media is also to blame, of course: immediate appeal is what sells, what draws clicks, rather than subdued, lay-of-the-land work that only reveals itself over multiple plays. We've also moved from photography that emphasizes golf courses from the level of the human eye (handheld cameras) to that which does so from hundreds of feet in the air. SFGC, for example, doesn't really look all that special from a drone, but it does so from the ground. Hypothetically, if the club's moto morphed into selling tee-times for TFE events, or topping Pebble Beach's ranking, then I'm sure they'd instruct the architect to rumple the bunkers, turf, and whatever else.
