That's a long time ago.

No, Debian has had identical runlevels 2-5 for many releases, nothing to do
with systemd.

I'm not quite sure what you're looking for - I've never tried Debian Buster,
but Devuan Beowulf works fine for me, and I happened yesterday to have to
install a sysvinit startup file (for zoneminder, which no longer comes with one
by default), which got installed using update-rc.d without any problem.

Devuan is based on Debian, and that project dropped LSB support in 2015:

You can have LSB, or you can have Debian/Devuan, but it's not easy to have
both.
