The 4th Dimension Update

The Mysterious Portal in Ancient Cities made of Reinforced Deepslate could lead to a 4th Dimension! What could this Dimension be? I’ll leave that up to Mojang, but my ideas are a dimension in the sky like the scraped Aether Dimension or a Dimension of Ice (Opposite of the Nether)! I also understand that Mojang is trying to make most of the current in-game places look better, and I could definitely see them updating the End Dimension next. So Mojang can feel free to add another dimension when everything has become more “lively” as they said. Thank You Mojang!
