In fact, I think many users/groups are useless. According to [1] and 
after checked groups used by udev:

  - groups "wheel", "operator", "staff", "lock", "netdev" and users
    "operator", "sync" can been safely removed

  - I think users/groups "daemon", "bin" and "sys" are now obsolete and
    can also been removed

  - "mail" and "www-data" should only exist if an MTA/webserver is
    enabled.

  - udev use "input" group (currently "input" group exist only if
    systemd is enabled)

  - group of /etc/shadow should be "shadow"

In add, since skeleton is now a real package we may define users and 
groups using SKELETON_USERS variable instead of maintaining 
passwd/group/shadow.

I can do these changes if there is a consensus on it.
