"root" holds a near religious status in the world of unix/linux server administration almost entirely because of the history of those OS's use as multiuser systems. back when your company, department, or college had a server the concept of being all powerful among dozens or hundreds meant something.
Now, especially in modern virtualization and/or cloud type environments, its almost a completely vestigial fear. More and more our servers are not only single user, they're single-application, tied together via network services. This is especially true in web clusters, your apache servers are your apache servers, your mysql servers are your mysql servers, it almost wouldn't matter if you ran them in single user mode and everything as root.
Obviously there are exceptions and we're not completely there yet, but the aura of power that tends to come along with the word "root" really applies to your vcenter password or aws private key these days more than a posix account on a few app servers.
