This does not happen with GNOME 3. At all. The only time I'm asked for
my root password is when I add or remove a printer, and
app-admin/system-config-printer-gnome has been doing this since the
very beginning. I'm still hoping that someone fix that thing.

With GNOME+systemd (and therefore, logind), the seat0 user gets
ownership of all removable devices (except printers, see above), and
the hardware buttons (poweroff, reset, suspend, etc.) No root password
asked. Ever.

You can see your seat with loginctl; if your seat is not seat0, that's
why your password is being asked. If it's seat0, then something else
is going on. Do you have pam_systemd.so enabled in /etc/pam.d?
