I don't buy this, given that root's login name is well known :)

If a system accepts remote root logins, an attacker need only guess
or intercept one thing -- the root password -- to log in with root
privileges.  If it does not accept remote root logins, that attacker
must guess or intercept three things:  the login name of a user in
the wheel group, that user's password, and also the root password.
