What's Next (Valley)?

I recently saw a couple of screenshot and a video of "Next Valley," which was presented as a potential new direction for the Windows desktop environment. I am guessing that these are mock-ups, maybe from just random people on the internet, but there was something compelling about a few of the features.

My question to the subreddit in general is whether there is any expectation of a "big" change like this happening under Windows 11 or is this just something that may never happen as Microsoft is trying to figure out a way to shoehorn AI (or whatever) down our throats?

To be clear, I am not loving everything about "Next Valley" but wish for just a little bit more customizability in W11 without resorting to weird hacks that mess other things up.
