Fair enough point, I also see it in normal English usage for proper nouns but basically nowhere else.
Wikipedia agrees with you (and also calls out the New Yorker vehemently disagrees which I find oddly comforting and hilarious)
In British English this usage has been considered obsolete for many years, and in US English, although it persisted for longer, it is now considered archaic as well.[3] Nevertheless, it is still used by the US magazine The New Yorker.[4]

Same here, I tried a number of arch derivatives and arch as well when I got a new desktop last year (after many years of mac work computers, iMac desktop for my kids, mostly Alpine images in the cloud/on k8s, and many many years of mostly Debian and fedora derivatives before I had kids and had time to putter around with *nix). Endeavor suited my needs (some local LLM stuff, personal browsing, a few OSS projects, and Steam) and yay has generally worked great to bridge the gap between pacman and aur.
