>The real issue isn’t with servers, it’s with desktop systems and laptops. When users plug in a USB sound card or plug their laptop into a dock, they don’t want to (and likely couldn’t) “easily script around” that; they expect an audio device, network connection, video card to be created without any user intervention, and go away when devices get unplugged.

Bingo !

Folks who know, and I mean really understand how to run servers know how to script init.

Folks who use Linux on the laptop / Admin Ubuntu do not and systemd makes them able to do stuff "most of the time"

There is no reason to force systemd as the default for servers. You dont plug things into servers and in fact you dont want some service monitoring servers so someone can stick something in a server and start rooting around it.
