Want to preface the following with this. The food mechanic as a whole has worked ok for me. Over the various alphas we've adjusted to changes, some bigger than others, but nothings been truly 'terrible' imo. While I really didn't like that cooked food could make you empty your guts, there were vitamins to combat it and thats been changed now. I'm also in the camp of wanting early game food to be relevant, even challenging, but not wanting food to be a long term everyday chore, I do mine and build quite a bit & from reports it looks like a19 (not playing it yet) will require more food and the 'right' drinks to do so, along with different perking strategies. Ok, adapt and overcome time again

So take the rest of this as simple musings of one player who isn't to fussed about things. (though I am still keeping my hopes up for really ornary zombie chickens)
Without spoilage, and I honestly don't care if its never added, then it seems inevitable that we'll wind up reaching a point where food just isn't an issue anymore, and you might not pick your crops for weeks. Saying that because I don't see a way to 'balance' food consumption/acquisition for widely varying playstyles. Player who doesn't mine, gets & uses vehicles early on, wears light armor and uses firearms vs. heavy armor wearing brawler who mines every night and has bad luck getting or doesn't really care if they have a vehicle.
If design wise TFPs are ok with food no longer being an issue by mid or later game then they could potentially do something like this;
Stage animal spawns. No large animals for the first couple weeks. Have large animals give quite a bit more meat than they do now. Could keep the dangerous night spawns and possibly tweak night time hunting as needed so SPs would have to be really hard core to attempt, while MPs could reasonably team together and be successful. Idea being to provide a way for MP to get enough meat so they'd be similar to SP who'd need to hunt small game for meat early on.
And if they're truly ok with overabundance later on then they could even possibly add in a 'baiting' bit or two; salt-licks for deer &/or corn~potato piles to lure pigs/bears.
Farming wise it'd make sense to me to have "tiers" of that as well. Something like
@Lemmers &
@Dracula said. If they bring back early-game/SP 'dirt farming' that requires a hoe I hope there'll be a no-perk/schematic stone version.
