Remember that in ICANN contracted TLDs and in some ccTLDs, a registry can only contact registrants by going through the registrars. While I can imagine some hack (EPP probably) for the registry to tell the registrar about inconsistent NS, I don't see the point. The lousy registrars won't care, the good ones could check and notify themselves if they want to. I suppose you could make a general observation that DNS operators can check for inconsistent NS and when practical warn the child operator but that sounds like "don't forget to brush your teeth" sort of advice.
