The way people use modern Linux systems is moving past how most people used Unix systems back in the day. Instead of piles of shell scripts glued together we now use a monolith (systemd) to manage most of the low level services and initialization. No one really cares or tries to setup proper multi-user systems and instead we focus on multiple roots with each application given an exclusive root filesystem, view of the system, etc. (i.e. containerized). Computing is a lot different than it was 50 years ago, and that's not a bad thing.
