This is a myth. I've explained what D-Bus usage in ladish (and LASH) is
in a recent mail to this mailing list.

Please take a look at the video. You are wrong. The radio button is
selected when app is started for first time, not when "session" is
started.

That sounds rather hazardous to me. To lose all of one's data instead
of saving it, after a potentially long session's work, because of a
check box incorrectly checked when starting the session, surely
wouldn't please many users? What I mean is: if the user starts an application
that has no
knowledge of LADI at all, and they check the level 1 box in ladish, is
that application then guaranteed to crash on session save and lose
their data because of an unhandled signal?
If user checks level 1 in ladish when starting the app, then ladish will
send SIGUSR1 to the app. If the app actually does not support level 1,
signal will be sent and chances are that default signal handler will be
executed. The default signal handler is to terminate the app. Applications
cannot register themself yet.
I think I must have misunderstood the use of D-BUS here, then. I had
thought that LADI was a D-BUS service which the application connected
to, so that LADI would know whether an application was running in a
"LADI-aware" state or not.
