Anyway, Devuan might not exist, it would only have been necessary to use systemd in the system of your choice. I have also seen many forums, in which they speak of its goodness .

It's far from immediately apparent to me that it'd be an advantage to anyone, although I must admit that I don't really see much advantage in the having of that information either. But a quick glance at a couple of other forums suggests that the common practice is to tell who are logged on to everyone.
Perhaps you have a compelling reason for us to be different?
