So privacy and security are relative, not absolute. I think this provides
better privacy compared to the use of MAC addresses for IIDs, but doesn't
provide as much privacy as RFC4941 addresses. If the level of privacy these
stable privacy addresses provides is not adequate, then you don't use them. You
either use RFC4941s, or you choose not to communicate at all.
Can you define the "privacy" you don't think it has any effect on?
