As a GM I honestly hate excessive bookkeeping regarding rations and inventory. Players need to take care of their own shit. We're here for adventures, not hardcore survival roleplay. I think it's a great spell because it removes the need for that bookkeeping as long as someone has it, and we can focus on scary monsters instead of resource spreadsheets.
And really, if the core of your conflict in your story revolves entirely around "ran out of food" when people walk around being able to literally conjure food like fantasy jesus, well, its bad writing, even in pen and paper. If people want to play hardcore survival with advanced wilderness rules then I won't stop them, but I won't play it or run it, its not fun to me.
