My main take away from it is that Gentoo has apparently lost so much mindshare, people don't remember it even exists or know what it does.

An ordinary Linux can be configured by installing pre-compiled packages. The system either has the package or not. Gentoo allows the package itself to be configured. Think of package ./configure arguments; they're abstracted as "USE flags" in Gentoo and allow tweaking the package internal configuration. It also allows modifying the environment variables used during the build. Setting CFLAGS/CXXFLAGS allows optimizing for the system's CPU instead of doing a generic x86-64 build.
Gentoo will give you that with proper package management including on the system part without having to do the weird dance you are making with abuild with a nicer experience if you want to patch and update your packages later and significantly better tracking on what you have done.
I have a hard time seeing anything starting from LFS which wouldn’t be better actually starting from Gentoo.
