App view is unsupported on sysVinit

SUMMARY
Hi, I'm testing on MX Linux now, and they are known to use sysvinit by default. 
What I noticed, is that plasma-systemmonitor is unable to show applications ("Applications view is unsupported on your system") when I'm in an init session, but it works when I'm in a systemd session. Is it possible to somehow bridge the two, so applications would show up on an init based system too?

STEPS TO REPRODUCE
1. Boot into a sysV init system
2. Launch System Monitor
3. Applications won't show up

OBSERVED RESULT
Applications view is unsupported on your system

EXPECTED RESULT
Applications view should be displayed on a non-systemd based system too.

Yup, this feature requires features in systemd.
Comment 2 Arjen Hiemstra 2024-07-03 10:14:53 UTC 
To elaborate a bit, what it requires specifically is a cgroup layout for processes that so far is only exposed by systemd. See https://systemd.io/DESKTOP_ENVIRONMENTS/ for the details, especially the section "XDG standardisation for Applications".
