I agree separating the domain knowledge (CMake, Meson, etc.) from the build plan executor (ninja) is extremely good too, but one must be fair this isn't itself

I agree separating the domain knowledge (CMake, Meson, etc.) from the build plan executor (ninja) is extremely good too, but one must be fair this isn't itself end-benefit to users. If good architecture was an immediate end-user benefit, we'd get a lot less bad architecture from short-sighted institutions writing code!
