This brings back memories, same here! I even bookmarked a page to remember how to rebuild the kernel because I can always expect it breaking.
I didn't really get into custom kernels until I started using Crux. A few years after I started using Arch I got sick of the rolling release and Arch's constant breakages, so I started looking into the alternatives, that brought me to Crux (which Arch was based off of) and Slackware (which was philosophically the opposite of Arch without sacrificing the base understanding of the OS). Crux would have probably won out…
The best successor I've found is Alpine. It's minimal and secure by design, has an excellent package manager (I much prefer apk to pacman or xbps, or apt and rpm for that matter), has stable and LTS releases while letting people who want to be rolling release do so by running edge. People think it's only for containers but it has every desktop package anyone would need, all up to date and well maintained. Their wiki isn't at Arch's level, but it's pretty damn good in its own right.
