Because if they didn't type --help, we are going to have to log the attempted 
compromise. Sending an audit event requires CAP_AUDIT_WRITE. You have to be 
setuid root from the beginning or not at all.

An unprivileged user cannot successfully use this utility. Just like tcpdump 
can't be used. The difference is that shadow-utils modifies a trusted database 
and tcpdump doesn't. 

If you need to see the command options, look at the man page. That's what its 
there for.
