mountains

It would not be great to have mountains of more than 500 blocks trying to scalarlass would be a challenge and more with the new goats this will be possible if you support me in this idea the height limit would reach 800 or 900 blocks so there can be space (that if a from height 600 you will not be able to plant vegetation nor can life exist only snow skeletons and polar bears it would also be good to guide us by sea level where the water can only be generated in layer 62 or if it is generated higher it will be frozen and If it is generated lower down (the caves) it will be darker if you support me in this idea I would appreciate it very much
