One does not edit anywhere near the number of configuration files and install enough software to justify running as root all the time by a long shot. This isn't the Windows world where over half the software requires running as Administrator just to function.
I spend months at a time never touching the root account on my systems after they've been set up. I haven't seen a box that enabled root logins in over a decade, from any vendor or Unix flavour.
So I call "bullshit" on the theory that there are users out there logging in as "root" for the sake of "convenience."
