Yeah, it was annoying for a bit of time, but not anymore! I haven't had systemd installed in quite some time. sysvinit works without a hitch on bullseye and bookworm.

added: Debian's (to me) about (among other things) technical superiority, a robust packaging system, as well as user freedom and choice. It's super easy to not use systemd these days, "what is debian" didn't change, there was just a slight delay in reality catching up to principles. :)
