Here is a starting point of a fairly accessible podcast or transcript if you don’t want to listen and links to a bunch of the research.

As someone who works in the industry designing and testing building products to resist fire, it's not as simple as just slapping non-combustible exterior cladding and roofing products on it.
A good case and point to this is the Scotch Creek Fire Department, had a corrugated steel roof and steel cladding, all exterior products non-combustible, still ended up being a smoking hole in the ground after the fire last year, and it wasn't even in a particularly dense part of the forest.
I think you missed the two most important parts of your link.
Firstly clearing out most of the vegetation within 100 feet of a structure. Imagine what these mountain towns would look like if we removed most of the vegetation.
and most importantly

Not to mention, many homeowners just kind of instinctively understand that the odds of being in a wildfire are extremely low. There are more than 40 million homes in wildfire-prone areas, and only a few thousand burn every year. Homeowners might decide it’s just not worth spending time and money to change their properties.

Maybe its acceptable not to mitigate every risk in every situation. If you live in the mountains, the probability of your property burning in your lifetime is next to 0.
