I would also reject this case (redirecting IPv6 to IPv4).
It adds unnecessary complexity to the Tor code and network setup to be
worth it. (At least in my opinion) the costs would be more than the
benefits.
Why not just listen on IPv6 as well instead of giving "IPv6" which is
really a tunneled IPv4 socket?
