The camp supplies feel janky because they were a reaction to dnd people wanting everyone to be forced to play the game as they play it. it feels out of place because it is. they should just remove all food if they're going to stick with the camp supply nonsense. I've spent more time in this playthrough micro-managing my inventory than ever before, and it's not fun. That's not gameplay. If you want to limit long-resting fine, do it. Make certain areas that you can't rest in. Remove fast travel. Adding in a weird supply mechanic that for some reason scales as you level up and you have to micro-manage isn't the solution.
