>4. Libsystemd is a problem for the ecosystem. People get dismissed as systemd haters for pointing this out but it's big, complicated, has a lot of dependencies and most programs use a tiny fraction of it. Encouraging every service to depend on it for initialization notifications is insane.

This is ridiculous, nobody "encourages" every service to depend on it for initialization notifications, you can implement the logic in 10 lines of code or less.
