Joking aside, I think this change is correct, but it would be great to
be able to have long-running unprivileged processes, as on systemd.
There, the administrator can use `loginctl enable-linger $USER`. We'd
want to do it in the system configuration. From loginctl(1):

------
Enable/disable user lingering for one or more users. If enabled for a
specific user, a user manager is spawned for the user at boot and kept
around after logouts. This allows users who are not logged in to run
long-running services. Takes one or more user names or numeric UIDs as
argument. If no argument is specified, enables/disables lingering for
the user of the session of the caller.
