That is one thing I never understood. I know that strict tracking of all resources (food, water, ammo, spell components, encumbrance, etc) can really turn people off these days but to completely eliminate ALL resources just seems like lazy design imo. There are times where limited resources can create adventures and tension on their own.
There is nothing stopping the DM from vetoing the ability (No Grog, you're in the desert/ badlands. You cant automatically find food, and/or you need to make a DC X survival check to do so').
That's what DM's are for.
Id rather they took the above approach, than include a complex table of how much food you find with a check result of X, divided by terrain types and so forth, plus meticulous bookeeping.
Eyeball it, make a ruling and move on.
