Disabling root login as a configuration option isn't near arrogant. If
they're able to edit gdm.conf/run gdm configurator, they're able to
login as root. Hopefully by that point they're able to see that it isn't
a brilliant idea anyway ;-).

This was my "I frankly don't care that it isn't Friday" line ;-).
Seriously, I have done quite some things with X and never had to resort
to this option, so I asked myself why you needed it.

Meep:

novice user 1: "It says I can do this as a normal user as well"
novice user 2: "Huh?"

Still you need to glue together many parts, tweak many settings, and
nothing you tell me needs to be done as root.

A good idea given the reasons others pointed out on this thread ;-).
