Developer comments
To be honest, I really don't like this idea. The clear separation between "user data/permissions" and administration is a very strong point in Unix/Linux, and we should keep it. Providing a button for "give me a super-power nautilus" is too blunt, and subverts
(a) our efforts to provide the necessary administrative bits through appropriate UI (like NetworkManager),
(b) our efforts to provide more fine-grained privileges (PolicyKit) and eventually get rid of gksu, and
(c) leads into the Administrator madness Windows users have to endure.
I'd rather collect use cases why users need to run nautilus as root in the first place, and eliminate those.
