Requiring compliance to an obsoleted RFC (6204) is...um...unusual. Especially since RFC 7084 fixed several items in 6204 that needed fixing. I, personally, would not recommend anything be compliant with RFC 6204.

Also note that DS-Lite and 6rd are "SHOULD" requirements in RFC 7084. It is totally possible for a device to be 100% compliant with RFC 7084 and not do either DS-Lite or 6rd. Surely mobile device manufacturers are intelligent enough to recognize that there is a very good reason for them not to do DS-Lite or 6rd (because these aren't used in 3GPP networks)? It would also be possible to explicitly note that these technologies are not used or needed for connecting to 3GPP networks.

It's my understanding that when an RFC is obsoleted by another RFC, readers are supposed to consider the new RFC as a replacement for the obsoleted RFC, every time they see a reference to the obsoleted RFC. So a brand new reference to an obsoleted RFC, for me, is rather bizarre. It's boggling my mind. I'm not convinced that this reference to an obsoleted RFC will be understood in the manner you intend.
