I'll be keeping an eye out for your DE. For a long time now, the Linux desktop space as a whole has been rather uninspired in my opinion. A few interesting ideas have surfaced within it but failed to become popular for one reason or another, making for a rather stale environment.
That's not to say that it needs to be in constant flux or to be full of radical ideas. If anything, it'd be nice to see more DEs settle into a design and feature set and chase stability, efficiency, and performance over shinies. Rather, I think it would be better if more Linux DEs were built around coherent, opinionated design philosophies that cleanly set them all apart from each other. Even if that design philosphy is just "N platform's desktop, refined to its ultimate form", it's better than the "aimless bag of features" direction that's most common.
IMHO if you can afford some setup time just skipping the DE entirely is still the best option. My i3wm setup plus some scripts and services was super lean and efficient. Still buried it for reasons I can't remember, switched distro too, but when I find the time I'm eager to create a tiling WM, wayland native UI on NixOS again.
Please can we just have Windows 98 again. Not the kernel, kernels are better now, but UIs have only gone downhill from there. Win9x was peak "it just works" (as long as it doesn't crash so please, no win9x kernels)
The real problem is you can’t have a DE separate from the programs that run therein, so everything just apes windows ;or sometimes macOS; badly.
To really break free you have build all the programs too, with the new UI paradigm.
