root login via gdm

[Pete Travis]

At one time, one could not log in to a GNOME session on Fedora as the
root account.   Now, you can, out of the box.  For me, this seems like
less of a "getting in the user's way" thing, and more of a common sense
default security policy - especially given all the work done to make
things work smoothly with polkit.  Am I missing something?  If not, what
about going back to blocking root login to desktop environments?
