The problem is really that RFC 3263 repeats "A or AAAA" - which means that if we follow RFC 3263 verbatim we won't have both IPv4 and IPv6 addresses to connect to. I have not claimed that it talks about how we connect.

It seems like no one can say whether this text is normative or not, which really means we have to clarify this, since developers will be (or already am) confused on how to implement properly.
