Given the interoperability issues cited by some, and the absence of standardization cited by others, I'd agree that IPv6 "endianness" ought to be standardized. While one can likely logically infer that IPv6 is big-endian, codifying it should eliminate doubt (leaving little to no room for debate/confusion, ala RFC 791, Appendix B for IPv4). Just my two cents...
