Decided to check out the new Biomes, and I was seeing what the top of the world would be like. This is what I've found. It's not game breaking but I pointed it out.

Edit: Turns out that even water pools, Pillager out posts, and ruined nether portals spawn aswell. I went into the nether and the same problem appeared again, instead only mushrooms were spawning. made sure to attach those.
Environment
My operating system is Windows 10, I have the 1.16.1 Nether Update Release of Minecraft. This was a randomly generated world.
