Now, if they fix Item Management, and/or they make it so that any spoiled food is just auto-dumped because it's worthless, then sure. I think that'd be a very good immersive thing to do, and it would greatly help to limit long resting via limiting your food supplies.
That would be a good idea. It is doubtful that we would need fertilizer for anything, so spoiled food should disappear from our inventory.
