One thing to note here is that restorecon becomes more dangerous with
your changes. Right now restorecon is relatively safe in that you can
only change file labels to their system default. It would probably be
acceptable in most environments to give users access to restorecon so
they could properly set labels for files in their home dir.
With your changes and this scenario, users could do something like
restorecon -p /home/foo /home/foo/sbin/unix_chkpwd
and start reading /etc/shadow.
So I am not sure this is the right way.
