I suspect people will get varying experiences with that. That they will
attempt to multi-home with teenie bits of v4 I don't disagree with but
that teenie bit better be part of a larger aggregate that can reach at
least one of their runs home. There will likely be considerable
filtration once there is enough dual-stack pressure put on gear, and v6
being where the growth is it will get priority. Dual-homing to their
ISP might be a compromise solution seen more often with v4 in that
scenario.
