OK

To achieve interoperability, canonicalisation MUST be done at
a single well-defined place in the DNS resolution process.  One 
could imagine either doing it in the client resolver or in 
the server.  Whichever place is selected, this must be 
really clearly specified for us to have global interoperability
with the DNS protocol.

Your proposal appears to say it is in the DNS resolver client.
If I understand your proposal, then in light of the interoperability
issue, the above quoted sentence needs to be changed to read:

         Canonicalisation MUST be implemented and performed in the 
         DNS client resolver such that all on-the-wire DNS requests and
         DNS replies are always in canonical form.
