It seems to me that what's happening is that systemd is now enforcing

for people to make use of what's underneath without viewing it through
the overlay... which, as it turns out, is a *very* common thing to do
(screen, tmux, nohup, etc.).
This is a very good observation. The 'login' infrastructure deals with
authorization to run processes on the computer, which is orthogonal to
managing characteristics of individual processes, such as whether they
are transient or persistent. Admitedly, the logout process has to deal
with the lingering processes: Windows, for instance, throws a dialog box
asking to terminate the apps. This is somehow a violation of layering
which I just pointed out above, but I think it is correct in asking for
user intent.
In any case, the common use case nowadays is a personal device, where
this whole issue is somehow moot: there are no multiple users, the user
is the administrator, and the login session is really from startup to
shutdown---so the proposed change doesn't change the user-visible
behavior much, except making the reboot quicker.
Actually, how does this proposal deal with network logins? If I SSH to
another system and run backup in the background, will it kill it when I
log out?
