If they make the food mechanic super convenient where food automatically teleports to a stash, doesn't ever weigh you down and is consumed automatically.. what's the point of it? If the purpose is to limit Long Resting? If it can't accomplish that, it's a redundant feature.
If it's in a stash somewhere and the amount would be limited to where it actually affects your decisions to rest or not.. you will then be surprised when your food stash is suddenly empty. Unless you go look in it regularly. Sounds really tedious.
I just can't see a win with BG3's food system. Probably why other games never used such. Or it will have to be changed into something like Pathfinder Kingmaker where it actually does weigh you down, but you can use skills to hunt during your travels. That said, even in P:K I didn't find it at all fun to have to crawl back to town starving.
They really need to find other solutions to limit Long Resting.
