Look to The Skies!

I'd love to see a skies update! I look around in Minecraft and everything has evolved so much, and as I find new and rediscovered love for things that we've had along the way, The Nether, The Sea, Jungles, Hunger, larger and more advanced caves, Bees, The End, Villages, Pillages, I see how it's all evolved and become better and more advanced. But one thing that still feels the same is the sky. It would be enchanting to see birds flying in the sky or roosting in trees, such as large oak trees, which often have exposed branches. In their nests, maybe you can harvest eggs from them. Another idea is dragon dens to trigger an Overworld boss fight. Or perhaps a powerful Roc, a giant, predatory bird seen in Middle Eastern mythology. I'd love to see maybe some floating island structures, with maybe villages or other structures on them. Maybe another kind of ruin. A sky ruin. Maybe giant tree structures that rise into the sky, perhaps a den for said Roc, too! What would be even cooler, would be seeing a floating island dimension, similar to the end, but with clear skies and overworld features. Perhaps a portal to this dimension could be on an island in the sky. There is so much potential for an update like this, and I'm sure it would be welcomed by the community. I'd really love to see what the Minecraft team could do with an idea like this!
