Over 60 years ago, 4 of us backpacked across the Grand Canyon--Since we didn't know how much wood we would find, I carried a full size Coleman 2 burner stove, and a gallon of white gas in my pack! As I got older, the gear became much lighter, to the point that now, I use rocks, no grate, a small lightweight pan--size depending on how many we are cooking for--and a frying pan lid. Often we use foil for wrapping food, and placing in the coals.
I was doing the AT or PCT, I would carry a small single burner multi fuel stove, and maybe titanium (good quality) pan and lid/frying pan. My understanding is that many places wood becomes scarce--and in some situations a fire may not be an option. There is something to be said for a a small group, vs solo, for a stove, and weight.
Aluminum is hard to "season" as a cast iron pan--but cast iron is too heavy.
