This is what I was thinking initially when doing it via a patch. I'll
attach a new diff with this added back.

Good catch. Duh, why didn't I think of this! xD

Fair point. This is a large escalation for a seemingly simple
operation. 

Does this read better?

To enable shutdown and reboot, the user should be in _shutdown group.
To enable suspend, the user needs to be able to run zzz(8).

Use usermod(8) to add the user to _shutdown group:

        # usermod -G _shutdown <username>

The user must be in group "wheel", and apmd(8) must be running 
to be able to run zzz(8):

        # rcctl enable apmd
        # rcctl start apmd
        # usermod -G wheel <username>

(It is also in the diff)
