Well as I've said if you can convince upstream I'll happily go with
that. I do not want to introduce patches for this, although I will be
happy enough with a workaround.

They can, and should be updated to call poweroff instead. Or better to
integrate into dbus and call things that way (which is needed to provide
nice warnings about other users/sessions etc. anyway).
