Your "separate utilities developed under systemd umbrella" claim was simply false.
Your attempted retort was even more funny, since many coreutils implementations can actually literally be built into a single binary with many symlinks, with dispatch done based on arg0. It's even the preferred packaging option.
There are a lot of interdependencies within those source trees. Nothing is self-contained. So the "itz just monorepo bro" is also false.
they also overreaching and that’s THE point?
You literally just listed multiple projects 🤭, where their collective surface is also nowhere close the the systemd forced hegemony. Maybe they should all unite and join the "umbrella".
