How is this a hack?   It correctly identifies all DHCPv6 packets.   The 
solution I've proposed is completely in compliance with RFC 7045.   If you want 
to argue that a solution is wrong, you should say what is wrong with it, not 
refer to it as a "hack" as if merely by calling it a "hack," you have somehow 
shown that it is not a good solution.

Er, no, the point of this is to _not_ break new transport protocols.   RFC 7045 
does not deprecate RFC 6564.   If you want to deprecate RFC 6564, please go do 
the work in the appropriate venue.   It's my understanding, however, that you 
already tried this, and did not get consensus to even adopt your proposal as a 
working group work item.
