There is difference between mandatory one implementation and set of funcionalities. Systemd is monolit with visible parts that provide somewhat modern
funcionalities in 'nix world.
And there is no serious developers in 'distro' space, except RedHat. And, really, there is no such thing RedHat we have in old Linux days - it was devoured and we just have a label doing corporate propaganda.
So when few modern init systems were hatching RH dropped systemd and, as RH is main force in distros development, it gained dominance.
And since then thing are getting worse.
Eg. cgroups ? systemd first used them and so much hype happened. But is it deserved hype ? No! They implemented cgroups v1 when cgroups v2 was available. And cgroups v2 usage was blocked for years. In systemd too.
Do not make mistake of not seeing difference between good and modern functionalities and one codebase with funding that block real development.
