I think polkit depends on dbus.

I believe freedesktop.org has adopted dbus to distribute
information, eg from the hotpluger.

Sure it does. Why not? sudo is the legacy Unix command to handle
fine-grained priviledge escalation. No need for policykit.
Don't edit /etc/sudoers directly, invoke visudo for that, it will
check the validity of the file before accepting it. To let it invoke
your preferred editor, first export EDITOR foo.
