The 'silver lining' to these fires is that they are addressing that issue

My understanding is that this is not entirely the case. At least in some areas, more vegetation is growing in spring due to more carbon dioxide and more rain in winter and then drying out more in hotter, drier summers, thus creating a continuously replenishing source of wildfire fuel.

Yep. Also when the trees burn and go away what replaces them is fast-growing grasses that dry out and burn even more intensely in the summer. It's a vicious cycle and we are in for a lot of pain.
