No to belittle or dwarf the importance of foraging, farming (upcoming), or fishing(love it).
But would be interesting to see 5% chance of looting a canned food item. Especially for junk piles far from water source, if you could loot say a soda or cola for thirst, maybe even BEER!!!^^ But also canned food items such as veggies, etc and SPAM .
Anyways a suggestion which isn't all to important but could be important... especially the salvaged booze
