The purpose of survival is to make the game challenging. When pressing F3 you are shown several variables that make the survival mode easier.
Location
Lighting levels
and a few more.
This is not a feature request because i am not asking for new additions, to me putting to much information in the debug UI in survival mode is a bug.
Sure, it's a feature request. If someone thinks those pieces of information make the game too easy, they can just not use F3. When designing something, knowing those values can be very helpful.
