The Final Frontier Update

Alright, hear me out: We are all waiting for a few promised and a few needed updates. I couldn't find a clear connection at first, but then I thought of this phrase: "The Final Frontier". These are the places that would be updated:

Deserts

Savanna

Badlands

The End

The Badlands, Deserts, and Savannas are all promised an update, and all three qualify for the saying "The Final Frontier". The End is also representative of when the saying is applied to outer space. Now here is what my proposal is: I'm sure Mojang already knows what they are doing for 1.20. However, if they do add these things in that update, I am simply suggesting a name that I feel would really apply here. In addition, perhaps there could be  second part, adding a new sculk dimension, with 25% Deep Dark, 25% Hollow, 25% Totemlands (The Stalker), and 25% Barrens (A completely empty biome with literally nothing; no resources, no mobs, NOTHING). The dimension could be 500 blocks in height, and be similar to the Nether, but with overworld-like caves, perhaps made of new blocks? I know it's a lot, and if you want me to separate these ideas, I can and will. Thank you for considering my idea.
