Another factor though is, many major router vendors still don't support
BCP38 or especially uRPF for that matter on all of their platforms in proper
fashion.

It's not a good thing when people ask you to do uRPF, and best your router
can do for IPv6 is only strict-mode uRPF which doesn't work too well with
multihomed customers or on peering and transit interfaces.  :)
