A use case draft should be the first step. Problem is, I have no trouble seeing uses for RH0, or whatever new scheme takes its place. The only problems I've seen mentioned repeatedly are the potential for DOS attacks in ISP nets. But ISP nets are not the only application for IPv6. So why don't ISPs simply filter out any RH0 traffic from their edge gateways, and leave it at that? And the rest of us can still make use of this tool, with no change required to RFC 2460. As always, there are workarounds like MPLS, if RH0 is eliminated. I'm having a hard time understanding why edge router filters don't work infinitely better than a mod to RFC 2460.
