So there’s not a full distro built around it, or even a full desktop environment, but you should check out niri. Keyboard focused, infinite scrolling, Wayland tiling window manager.
There is a nixOS flake or it can be installed over Arch, Ubuntu, or whatever else you want.
The good news is that something like this already exists; just goes to show it’s a matter of time before more refined options are developed.
As an aside, there are now plugins for Noctalia Shell, including a pretty good “Keybind Cheatsheet” plugin, which may make it easier to pick up and play with things like niri.
