I don't see any major adjustments happening, the food rest system is what it is.
Essentially resources in BG3 are extremely plentiful to say the least. Fresh food is laying round everywhere, as is gold, and magical items. It's so easy to acquire gold that it really has no meaning. Finding magic items provides no excitement as they are literally everywhere. Personally I never bother with food as there is more than enough CS lying about or lootable not to mention it can be purchased from multiple vendors. Since I have more gold than I know what to do with buying it has negligible effects on my vast wealth.
Having said that I know why the developers (of the vast majority of games) so generously lace their worlds with treasure. A more realistic approach would confront the player with real economic scarcity and insecurity, but who wants to escape to that world?
I LR and SR when it feels right because there is no real imperative to do otherwise.
