Death lands

so I was thinking all our biomes are passive imagine there was a non passive biome that would give you hunger or a bad effect but if you sleep in it you will become immune to its bad effect. But if you go in another death lands you will not be immune. You could build an ultimate base which would be hard for other players and mobs to raid (mobs also get effected) plants will not grow only berries will grow and water will be replaced with lava so if you walk in the dead lands with a water bucket it will turn into a lava bucket and instead of water rivers there would be lava rivers. This my second request for Minecraft to add my other one is a fishing net.
