I think the national park service fully accepted the idea that we should let fires burn around the lsat great Yellowstone fire, maybe 1990ish.

I don't know that they speak for the US Forest Service though. Between the different national level parks and forest services and then the state level ones, I wouldn't be at all surprised if there are still a lot in the active suppression camp. Then there are municipalities where people can basically live in the WUI and the idea of preserving only structures is further complicated.
