No no suspend/hibernate; but the goal it that it will continue to work
with openbsd and other systems that have no support for Xfpm (and can
thus ship without it).

If they want support for power actions with upower/pol/console-kit;
then yes. And indeed, Xfpm will be part of the 4.10 cycle.

No, we don't.; GtkApplication appeared in gtk3 IIRC.

Like I said, Xfpm has to move to core; which means git repo moves to
/xfce/ and we ship it with the release tarball. You can still do your
own releases of course.
