RFC 6145 has limited use for the cases for IPv6 - > IPv4 since it is 1:1 mapping. Most people do IPv6 because IPv4 is limited, so ... doing 1:1 mapping does not really buy you anything. You can just use IPv4 and achieve the same scale. The best use case i have seen for RFC 6145 is for the data center environment http://fud.no/talks/20120417-RIPE64-The_Case_for_IPv6_Only_Data_Centres.pdf as well as the mapping of the entire IPv4 internet into IPv6 as is the case of 464XLAT CLAT in the IPv4->IPv6 scenario.
