There is always room for improvement. Always. Even if I hadn't seen any games in which spoilage is actually functional, I would be certain of that.
Since you are interested:
Subnautica, Subsistence, Don't Starve, ONI, Ark, Rimworld, Fallout 76, Project Zomboid, SCUM, The Forest, Stranded Deep, Outward, The Long Dark, DayZ, State of Decay, Metal Gear Survive, Neo Scavenger, Green Hell - are some that I can remember.
Yes, food spoilage is far more popular than most of you believe. Naturally some of these games implement it better than others - but in every single of these games it serves a practical gameplay purpose, which is also missing here.
