Actually it will result in more query traffic once you have a client
trying to look up that name.  Now if the COM registry required
registrars to verify that the zone was configured on the to be
delegated nameservers before the delegation was accepted, delegations
like this would be blocked.

Some TLD's can do this.  Why can't COM?
