Isn't this a misdirection?   

I suspect it's more like: any (address family agnostic) clients of a dual 
stacked nameserver will (non?) deterministically lose IPv6 connectivity to 
DNS-determined destinations.

ie, even if I only send DNS over IPv6 to my recursive nameserver, if it is dual 
stacked (often beyond my control), and for this specific query it prefers IPv4, 
then I will not get an answer for my AAAA under this proposal.
