Either way, for usera to grant access for certain users to usera's files 
via group permissions requires sysadmin whether Debian or RH.

Neither is sloppy. You may feel that RH's creates more clutter compared 
to Debian's all new users belong to one group but it does not create 
sloppy security. The sysadmin can still create either scenario in either 
distro but both will still need per user groups to allow user to limit 
access to certain other users only via group permissions.
