You are welcome to rule it any which way you want. Myself I changed the entire rest and recovery system tying it to the exhuastion track.I refer you to my previous answer.
I take issue when someone argues on the side that 5e is NOT easy mode claiming one HAS to rest in a city or otherwise kill ALL vermin in a forest. THOSE are not the rules of 5e. That is not arguing from an honest account of 5e.
You cannot argue 5e is not easy mode when you are challenging with homebrewery.
