I dislike overloading systemd with tools that are not related to running services but systemd does the "run services" (and auxiliary stuff like "make sure mount service uses is up before it is started" or "restart it if it dies" and hundred other things that are very service or use-case specific) very, very well and I used maybe 4 different alternatives across last 20 years
But frankly if goal is to learn people about how Linux works, having SysV there is opposite to that goal
