New Difficulty Mode: "Survivalist"

Minecraft being a sandbox game that is accessible to many different playstyles creates some limitations when it comes to adding things such as smarter enemy ai, weather conditions affecting the player or tweaking overpowered tools like elytras.

I think a new "extreme" difficulty mode would solve this problem. This new mode would focus more on surviving from the elements and other dangers of the world. It could balance and change features more freely, without worrying about it affecting players not looking for a challenge.
