I don't get the hype for scrolling WMs. It feels like the app switcher view on phones. Never thought I needed that on desktop, normally it just freaks me out with how much stuff is open.
If you like this, check out stacked tiling. It comes natively in COSMIC and I believe it can be configured in i3, Sway and Hyprland as well. It's basically tabs across windows, but thanks to tiling you have different regions of the screen with their own tab sets. I usually just split the screen vertically once, so I have a left and right region. Turns out so many workflows can be described as 'ingest information somewhere and apply it somewhere else', and this is just such a useful layout for this. Whenever I have something that requires sole attention, I just maximize that window.
If you are looking for some reasoning behind the "hype": one piece of it is that humans have relatively good contextual spatial memory and using one very large "space" that has a sort of "physicality" to it (you can scroll it; things generally stay where you put them; etc) can feel really good. It goes back to some of the early ideals of "spatial navigation" of the original "desktop metaphor". (Many of which have been somewhat lost to time, with a lot less emphasis on things like windows opening in the same appearance as when they were last closed.)
I think where scrolling WMs starts to feel like it scratches peculiar itches the most is when you have a complex multi-workspace config in a more traditional tiling WM. Each workspace is a different place. In some of the best cases the WM may give a metaphor that each workspace is on a cube or other polygon that you are switching faces on. Scrolling WMs simplify needing to do 3D compositing if you want to visualize that "space" at a distance or have nice flips between workspaces that provide spatial cues to your brain, because scrolling is a thing we do a lot. We have many apps with "infinite scrolling" today; applying that to one large workspace can feel like a nice space to have to arrange your windows in, and other common computer gestures like zoom out and then back in to a different part of it feel "natural". Navigating your "desktop" becomes just like navigating a large Excel file or a large code file.
