I agree with this being potentially useful. I have a (very silly, admittedly) mod which is naturally incompatible with any mods that add new science packs. While I can manually add compatibility, or just flag incompatibility, it is impractical to flag every single mod which adds new science packs ...

seeing the spoiling items now makes me wonder if fish is going to spoil... that would be kind of funny, actually. make raw fish spoil, and have it be crafted into canned fish for long term storage to consume later.

feels weird with the stack of 100 fish just flopping in my pockets.
