Would there a downside to specifying both (enabling ipv6) on a machine
that doesn't support it? If not I'd suggest making -i equivalent to
tcp_ip_socket = true. I don't think it's too much to ask people to use
the preferred method to obtain maximum functionality.

If there is no downside to allowing both, probably both. If there is a
downside then ipv4, since it much more likely to be the default on OS's
for the next release or two.
