Well... some think it's a good idea, and there is an IETF draft, which
largely failed to get support.

I think it's a very bad idea to have stronger requirements on IPv6 mail 
than on IPv4, as it is yet another obstacle to IPv6 deployment - but 
maybe that's just me, and I have a slighly different focus than most
religious anti-spammers.
