I think that is a violation. I don't think that allows us to make more

No, but if Amazon were to make a decision about how to implement IPv6 in
EC2 and how to make the Metadata API service work with IPv6 we'd be
supporting two implementations - the one we came up with and one for
supporting the way Amazon implemented it.
