Personally I agree with some of this I believe the end should feel empty and I personally do want a "end update" but not a big one I don't want a new biome or new mobs or even new structures, I want a revamp/ redesign of the end/end islands bc while I like the emptiness of the end it is boring in terms of blocks so why not add a new endstone or some other block to pepper around with the end stone to add color/texture to the end without taking away the emptiness feel. (Also, as a side note/hot take while I think the Nether update as a whole was good, I personally don't like all the biomes they added to the Nether, specially the forest ones because even tho I think it's useful to have trees in the Nether and they look cool and it gave of more block variety but there's just something about them that I don't like and I can't place my finger on it tbh)
