The correct fix to this will be to just stop making IP6.INT
queries.
The best think that could be done is for the PTB to install
"IP6.INT. DNAME IP6.ARPA." *now*. This will allow the legacy
resolvers to get a answer and allow vendors to stop shipping
legacy aware resolver in the vague hope that they will get
a answer from IP6.INT that they didn't get from IP6.ARPA.
