I would prefer to see the "empty field" intention implicit in "MX 0 ."  
codified with more generality, so that (to give just two examples) it  
can also be used in the MNAME field of SOA RDATA to indicate "I do not  
accept dynamic updates", or in the RNAME to indicate "there is no  
mailbox published in this RR".
