I cannot believe that the point was that because new users would be created with their own uid and gid and their home directory ownership set to the same makes a system more sloppy security wise. Other than this facilitating the future use/need for usera to allow only select users to access some of usera's files, it makes no difference to the 'security sloppiness' of the system.
