Mark, I agree that DNS stuff which doesn't support EDNS is broken.  
However there's no standards-track RFC that says "thou MUST implement  
ENDS" or "those that don't are broken". This was why Lawrence and I  
came up with draft-ietf-enum-edns0-00.txt. The prime motivation for  
that was to ensure handset manufacturers and the like put EDNS  
support in their ENUM-aware resolvers. Since there's currently no  
other IETF document that says they should do this, they won't add  
this to the handset firmware or whatever.
