So rather than ask Larian to force my opinion on others, I would instead petition for more options so that everyone can tweak the rules to their own tastes. The above would let me play the way I want to. What other options would be needed to let others play the way they wanted to?
I am not a fan of treating the campaign like a creativity toy. Larian designs campaign and it needs ruleset that will make this campaign work well - that means pacing rests and encouraging engagement with mechanics. If food made combat to easy, and made some ignore core mechnics, like rests, healing spells or items designed for that purpose, then it wasn't a good implimentation. Sure, allow flexible modding if people want to mess with the ruleset, but out of the box it should be well designed - not asking players to DM the campaign.
Current system encourages people to take advantage of both short and long rest while potential food limit might discourage from spamming long rest too often. Overall a better experience for all I would think. Not perfect, but better. Better is good.
