I'm sorry, but if you can easily stack up three levels of exhaustion after three fights, and long rest removes one level each... There is no way in hell I'd accept that. That's among the most unnecessary mechanics I've ever heard of. It adds nothing of value and makes stealing from merchants a necessity if you don't want to hoard food.
With the bug in the game that makes my items in camp disappear, I'd be literally unplayable right now. Not without robbing the halfling merchant blind every.single.day.
