i didn't read all the original post because it's quite a lot. i will chime in and say, late July 2018 i drove through Canada into Alaska, about a day or so before i got to Whitehorse, i was driving along a pretty long lake, and on the other side of it, i saw a fire burning. my estimate would say it was less than a hundred acres, could have been a thousand tho' as it was far away and it's hard to judge from a distance. but i am a surveryor if that helps you feel better about my guestimate. about 30 miles or so before i saw it, i just happen to see a sign that stated "please report wildfires". obviously canada is very remote and after i convinced myself i should really call it in, i had no service. i drove for quite a while (several hours before having service) and then lost the inclination to do so. assuming surely someone else had by then. after spending about 3-4 weeks up north i started back to the 48, and damn if all of Canada wasn't on fire. i drove like 5 days in a haze thicker in some areas, thinner in others, but it was always hazy, it didn't clear til i got to the pacific a little north of vancouver. i always felt bad about that, even though i''m pretty certain the fire i saw way up in the yukon had little to do with the one that torched Alberta and BC, it made me rethink my efforts in reporting the next fire i may see.
i grew up and live in Desoto National forest in south mississippi, control burns have taken place since i was a kid. i know longleaf pine has adapted to fire. while slash and lobblolly isn't as tolerant. naturally, they grew in the branches, while the longleaf would cover the ridges where the fire would be the worst.
it's not hard to imagine in the image which one has a better chance to survive fire. anyway, it's plain to see that fire has always been apart of nature. as the OP did acually address. Desoto forest and lets say yosemite are vastly different and i don't know much about sequoias and other species that exist there, other than seeing them in person briefly. i know they are impressive. and where i live in the pine belt was logged to oblivion in the 1800's to a point where there is no native growth that remains. aside from some oaks, magnolia and cypress that are pretty damn impressive. the biggest pine i've seen with my own two eyes i'd say 2 people could easily wrap their arms around. i've seen some old local pictures that would rival the sequoia
i'm not a tree hugger by any means, but it's a shame all those trees were cut. now they don't get much more than about 30" or less before theyre cut. and before you say "them damn conservatives" your precious democrats cut them too.

anyway, about the fires, i dont think forest management is really going to help too much to be honest. we burn in mississippi about every 3=5 years or so on rotation. i don't think you can do that out west. i do agree there is probably more fires now than there was 100 years ago. i doubt there are that many hardcore denialists about things concerning the fact that we need to take better care of the enviroment. i think the biggest problem is the Al Gore worshiper type that think he(Al Gore) has planet earth in his best interest and go all bloodshot eyed and scream at you with a bullhorn for using a plastic straw. you're not going to strip the world of plastics and electricity until you find a better alternative. and that probably wont happen because no body likes being screamed at through a bullhorn. especially when it's made of plastic and uses electricity. everyone wants the light on when they hit the switch, and they cry like a baby if it's over 72 in the house with like 15 can lights in the kitchen burning so they can see good enough to put their poptart in the microwave.
