My guess is that since the Random MD5 generated LAN IID is “stable” and OS vendors have the option of disabling the temporary address - once that is done you now have a “stable” random IID and best of both worlds ; single traceable IPv6 address for incoming and outgoing connections for operations as the IID does not change ; unless the device moves to a different LAN drop ; with random MD5 hash generated LAN IID you have the user privacy concerns met. I did notice that RFC 7217 also does not preclude use of temporary address. So that is even more reason to stay course with RFC 4941. > >> > >> > Anyway, I hope we're all agreed that this topic, however >> interesting is not worth more than a small comment in RFC4941bis.
