It's not as bad as you think: the important package is systemd-sysv.
In buster:
$ apt-cache rdepends systemd-sysv
<systemd-sysv>
In bullseye:
systemd-sysv
Reverse Depends:
systemd-cron
dbus-user-session
|xfce4-session
|unattended-upgrades
sysvinit-core

libvirt-daemon-system
udev
libpam-systemd

prometheus-bind-exporter
prometheus-apache-exporter
prometheus-alertmanager

pk4
|numad
munin
micro-httpd
mender-client
|mandos
logrotate
dbus-user-session
|libguestfs0
|init
gpsd
friendly-recovery
exim4-base
The lines marked with a | have an alternative, e.g. numad has
..., systemd-sysv | cgmanager, ...
Several of these are not Depends, but Conflicts/Replaces relationships, but
I have no idea how to quickly filter them, and several like exim4-base have
alternatives, but these aren't shown here.
What I can confirm depends on systemd-sysv are
- systemd-cron (not relevant, we have cron)
- dbus-user-session (can be replaced by dbus-x11, although apt doesn't
find that solution)
- libvirt-daemon-system (real problem)
- udev (not relevant, we have eudev)
- libpam-systemd (not relevant, that is the integration for
dbus-user-session & co)
So the only real issues at the moment are libvirt-daemon-system and apt
needing a manual poke when installing something that pulls in
dbus-user-session, such as libgtk.
