Nice try at proposing good changes. I personally I would like to see some more realism when it comes to some issues, like:
I would add that meat should be preserved for at least a few months in sub-zero temperatures (like in real life, you can keep raw meat in freezer without it spoiling)
When it comes to your suggestions, Idk some things do seem more fun, like the wolf fleeing by you pointing something at it, it only makes sense where a wolf attacks you while you're harvesting by the fire.
Also it is possible in real life to starve during the day and just eat full meal in the evening, many people actually employ this tactic as a way of life. What I would like to see is minus calories, that is - you could loose fat/muscle (and some benefits with it) when you starve (instead of loosing condition by starving for a few days)
I actually get sort of in-game cabin fewer if I spend too much time (without passing) indoors, so I think Cabin Fewer is real, but it should definitely be more flexible.
When it comes to traversing steep terrains - think Alex Honnold! It's been proven it's possible in real life. I think traversing equivalent mountains to TLD would be a joke to him.
