So this looks like a spite fork intended to make a point, not likely to become a widely used fork of systemd.
However, 1) he is right, and 2) systemd's recent full-throated embrace of AI for programming make it clear that systemd really is in dire need of a fork. This project has gone full corporate insanity.
I was never one of the vocal anti-systemd folks (I think it's a huge improvement over SysV-style boot stuff), but the risk of this project was always the monoculture aspect. It's on approximately every Linux install, and it's going bad FAST.
