Being the one "guilty" of wpa_supplicant updates i don't have a strong
opinion on this either.
On one side wpa_supplicant has it's own way of controlling itself via
wpa_cli and thus somewhat negates the need for dbus bindings.
On the other side you may not want to fork to call wpa_cli and/or learn
the wpa_supplicant/cli controlling protocol (or other good reasons), and
if you already have dbus enabled those extra 24k probably won't hurt
that much in the global scheme of things - after all people who want to
save that last KB will probably steer away from dbus.
Regards.
