That might have been true a decade ago. I don’t actually know. I do know that modern init scripts for modern alternatives to systemd are barely longer than systemd service scripts though. So that’s kind of an insane take.
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.
