It didn't. You can still write your init scripts.

I'm not a fan of the monolith here, I dislike the whole concept of binary logs, of tight coupling with udev and journald, but seriously - once you get into how the various systemd service and target files hang together it's a (comparative) delight. And they can still trigger your scripts.
