So I came on after the update, and saw the whole /res changebiome. I currently have an "End-Themed" Residence, so I thought "Why not make it actually like the End?" Unfortunately, The End isn't listed there. Why is this? Since the whole part of obsidian pillars and the dragon lie in the End World, the only affected parts are that endermen are the only mob that naturally spawn (doesn't affect anything, we already don't have any mob spawns), along with a dark grey sky (kind of what I wanted to add more of an "End" - like effect to my residence). So why is it unavailable to us?
