1,2,3,4,6,12 - I don't like. 1-4 are not hurting the game in any sense and food is good for sale or decorating your camp. The thing that does hurt the game though, is that a skeleton might have a bone on it or it might have a rare magical ring on it, and you never know. So I can kinda feel that 4 could be adressed in some way, like, by introducing perception checks to spot treasure among the mundane. For now it really is searching every container not to miss anything, making some gold in the process. 12 is intuitive and helps to keep things realistic, with no potion and scrolls juggling at 20m range in combat.
The others I agree with and especially 5 and 7. And it is definitely a good idea to address all those once again.
