Idk... I like the idea of camp supplies. I think camping shouldn't be overused. What they need to fix is rest-based cutscenes and food management. Too many companion dialogues are locked behind long-rests. It would be a lot better if these dialogues were activated after a short rest too (unless you are in an area of immediate danger, or the dialogue is in reference to sleeping like Astarion's). Since food no longer heals you, picking up food should send it straight to the campfire, which should have its own inventory, rather than going in a party member's bag. Or, they should add a 'deposit all food' shortcut in the inventory, so that you can still sell food to a vendor if you wish to.
I really like tying spell-slot regen and health regen to an exhaustion mechanic. I think they should go full-fledged with an exhaustion mechanic that reduces movement speed and gives disadvantage on rolls if you spend too long without resting at all, similar to being encumbered. Narratively, Larian is constantly bringing up the intense need to get rid of the tadpole and counter-arguing that with suggestions and objections to resting throughout the party, but it never goes beyond that, and I think it would beef up the gameplay element for there to be another looming threat of tiredness on top of the party's immediate problem of the tadpole.
