It does, but for desktops it's not the most important thing to assign
resources permissions. Groups are static, and you want dynamic
behavior to properly support multiuser systems.

Your seat seems to be the owner of both the power buttons and USB
devices, so you should not be asked for a password when powering down
the machine (unless another user or root is logged in, for example by
ssh), nor when using a USB stick.

I repeat my question (if you already answered I apologize), do you
have systemd emerged with the policykit USE flag?

Regards.
