I agree with Nick that this probably is the best option we have. 

One note though: I might have missed something in the discussion but
the separate service you are talking about doesn't have to be a
separate app, does it? You could simply make xfce4-power-manager a
simple power management service that runs in the background and
provides suspend/hibernate/shutdown/reboot/(logout?) methods (with
error reporting) to other applications like the session manager over
D-Bus.

Depends on how complex the interaction with upower and PolicyKit is.
dbus-binding-tool is able to generate stubs for calling methods on
D-Bus proxy objects without too much extra code, so maybe that would be
enough?
