I have been using xfce4 on Gentoo for about 16 months. It
never needed upower, consolekit, or policykit. (Those never
came up as dependencies of any xfce4 packages.)
I am about to install xfce4-4.10 on another system,
and those three packages came up as dependencies
of xfce4-meta-4.10. Any idea what USE flag might be pulling
them in?
