Well, you could configure your desktop this way on basically any linux distro!
Theres nothing special about Arch that makes this easier, just the vague feeling of superiority that comes with having made it on a distro that prides itself on not being user friendly(and the fact that obscure packages are usually in the AUR).
I had a pretty radical wayfire + sawfish + crystal dock setup on opensuse tumbleweed for a while. Opensuse has OBS, which is basically like AUR but more user friendly and with a bit more security. But I didnt need it, since they had everything I wanted in the main repo.

Great article. Exept the part where it was written by chatgpt. Imagine my surprise when I wanted to click on the link at the bottom where its supposed to link to UK ministers response, and the link ends with source:chatgpt!
