This is not really true, and if you'd like to learn more than you ever wanted to know about this topic then you should start following Zeke Lunder from The Lookout and review some of his wildfire analysis videos on YouTube. He often talks about the idea of "good fire". Not all fire is "good fire". A lot of megafires, the kind that might be sparked by an arson technique ignorant of modern wildfire management practices, do not necessarily lead to "good fire". They may at certain stages (especially when wind dies down) exhibit some traits of "good fire", but for the most part, these are forests that are the way they are due to too much suppression for too long, and now require "good fire" if our goal is to still have a healthy forest after the fire. An arson that starts a megafire is going to potentially transition to a very different type of forest, or an un-forested wasteland, as seen in various places in the Sierra foothills and SoCal.
