Somebody call the Wahhhmbulance. This guy is outmoded. How about expanded security permissions for small groups of people in a larger directory? How about PAM auth plugins? How about escalation preventiontion for those same people, PLUS auditing instead of just seeing "root did something dumb".
I don't even get why this gent even bothered to wine and complain about this except that he doesn't "get it". This has been a solved issue for over 20 years now, and you don't see large swathes of folks bitching and moaning about sudo at all.
