Trouble with ModemManager

Users of EasyOS will have seen this on-screen message at every shutdown:

ModemManager: could not acquire the org.freedesktop.ModemManager1 service name

This has been there ever since Easy started using NetworkManager (NM) and ModemManager (MM), which is going back a couple of years. Let's see, it was late in 2018:

I took it out for awhile:

Then it went back in, and stayed in. It works well, mostly flawlessly, and many users of Easy have expressed how they like it.

NM starts the MM daemon, but I have no idea if MM works. It is supposed to be for modems, like those 3G USB modems that we used many years ago. Maybe it talks to router modems also. I don't know, never looked into it. Here is the MM homepage:

That "org.freedesktop.ModemManager1" service name is a dbus thing. From a bit of reading, it seems that MM is hardcoded to need systemd for the dbus connection to work. I wonder if the Slackware guys have done anything special to get it to work with dbus without systemd?

I don't know if it is a daemon that is just sitting there, dead weight, unusable. I could just remove the MM package, as Easy still has all of the Puppy tools for modem connection.
