More Bosses

So I am aware that there is already some bosses in Minecraft and they are great, however. There isn't enough in my opinion so I think that with the new Sift dimension you awesome people could add in a new boss or something. I don't have any amazing ideas but maybe like add a certain biome in the Sift and make it so there is like an underwater boss (that would be awesome). Also this is a hot take but there should only we 1 Warden that spawns at a time and it should have a health bar but that's just me. Thanks Mojang Minecraft is awesome.
