I would push back for a slightly different reason...

Any inability to forward IPv6 might not impact the IPv4 peering session =
and
you might run into a situation where the peering session stays up and =
continues
exchanging routes, but the traffic cannot pass (or cannot pass in one =
direction
which is even more fun to diagnose).
