These two just introduced a subtile behaviour change during stable series,
possibly (not likely) leading to DoS opportunities from applications running
as gid 0. Really, with capabilities first and now selinux we have moved
away from treating uid 0 special, so introducing special casing of a gid
now is more than just braindead.
