Before the ArchLinux wiki became as good as it is, people like me used the Gentoo and LFS wikis as documentation for Linux.
There isn’t quite enough time in the world for me to be able to use LFS in anger as much I would wish. We make do with source distros with source managers like Gentoo (surprise!), Funtoo and others which give the source distros users just enough helping hands of dependency management.
Real tears would be shed were for LFS to disappear.
Everyone does it. Every year of so we gather everyone we know together to commemorate.
