I am on the fence about spoilage. The thing I hate the most about survival games is accidently burning food you are cooking. 7d2d keeps that from being a pain in the butt, but spoilage of cooked food seems like a fair addition. Once I have my water and food loop figured out, I usually have stacks of bacon and eggs by day 7. Food and water become a complete non issue for me.
Now as a solo player, this might feel like a good thing. Less micromanaging, but as a group Co op game, this might take some of the fun out of being the "chef"
If they do add spoilage, hopefully they add a craftable cooler spoils at 25% rate and a fridge that stops it completely but requires electricity otherwise it functions as a cooler.
