No, of course not, it uses the org.gnome.SessionManager, they've
had that for years[1]. It's just recently that they started
removing XSMP support[2] breaking session management on Xfce, KDE
and anything non-GNOME. What's worse is that the "Unix" backend
of GtkApplication has the org.gnome.SessionManager DBUS interface
hardcoded[3] for session management and the GTK documentation
actively encourages people to remove XSMP support in facor of
GNOME-only session management[4].

Sorry don't know, but they will have to come up with something
for their Wayland support. What I do know is that they have an
abstraction of XSMP support in the KDE core libraries still used
by many KDE applications, so I now use Okular instead of Evince
in order not to loose all my open PDF's when I log out...
