I can't reproduce any of this (on an up-to-date jessie system).
Xfce
====
When logged into an Xfce session, I have the following output from
systemd-inhibit:
Who: NetworkManager (UID 0/root, PID 23444/NetworkManager)
What: sleep
Why: NetworkManager muss Netzwerke abschalten
Mode: delay
Who: xfce4-power-manager (UID 1001/test, PID 2545/xfce4-power-man)
What:

Why: xfce4-power-manager handles these events
Mode: block
Who: Telepathy (UID 1001/test, PID 2634/mission-control)
What: shutdown:sleep
Why: Disconnecting IM accounts before suspend/shutdown...
Mode: delay
3 inhibitors listed.
xfce4-power-manager correctly takes the inhibitor locks as outlined in
[1] and whatever action is configured to happen on various events is
correctly executed. For testing purposes I set the action on power
button press to ignore, and the result was, that simply nothing happened.

gnome-settings-daemon correctly takes the inhibitor locks and everything
works as configured in gnome-control-center

Same picture here, KDE works just as configured in the desktop session
acpi-support
============
acpi-support checks if systemd-logind is in use, and exits in this case.
See /etc/acpi/powerbtn-acpi-support.sh:
if { CheckPolicy || HasLogindAndSystemd1Manager; }; then
exit 0
fi
As far as I could test, everything just works.
