Factors, actions influencing the possibility/timing of IDR for IPv6-basedrouting domains?

I'm not sure of this being a real problem, at least not the situation
you describe.  In your example a client has IPv6-only, and gets to
IPv4 via NAT64 at some point in the network path.  I think in this
scenario we would just serve AAAAs to these IPv6-only networks and
side-step the whole issue.
