Sure, that seems pretty reasonable. Here’s the init script for sddm:
#!/usr/bin/openrc-run
supervisor=supervise-daemon
command="/usr/bin/sddm"
depend() {
need localmount
after bootmisc consolefont modules netmount
after ypbind autofs openvpn gpm lircmd
after quota keymaps
before alsasound
want logind
use xfs
provide xdm display-manager
}
That’s it. That’s the whole thing.
That’s a pretty simple one though, so here’s Alsa. It’s a more complex one:

That’s definitely longer than a systemd service, but you’d have to write an awful lot of them to be more code than all of systemd. Overall the entire /etc/init.d folder on my PC where all the init scripts even for the stuff I’m not using are stored is a grand total of 147.7 KiB. Not exactly an unmanageable amount of code, in my humble opinion.
Its certainly easier to read than most old init scripts and I can see why some distros and openbsd would pick it over systemd for more control. I’m not likely to pick a distro that uses it anytime soon, but i can see why some do.
can you give examples of some? Not trying to bd sarcastic, i do just want to see what alternatives are doing.
