Personally I support this draft. But would like to see stable privacy enhanced addresses as a replacement for IEEE-based addresses since they allow an attacker to infer to the vendor of a NIC. On OUIs of Apple Inc. they also allow conclusion to the operating system. Thus an attacker gets more information by an IPv6 address than they should in my opinion.
