Essentially RFC 3941 is generating random interface IDs. (There
are practical issues, but really they are about what should be
random working and not e.g. having two nodes use the same PRNG
and repeatedly clash.) It is a solution that is not using EUI-64
(except as a part of a seed for the random process) to ensure
uniqueness. And all I said was that the EUI-64 solution isn't
acceptable in some cases.

Sorry, typo. RFC 4941 obsoletes RFC 3041.
RFC 4941 adopted recommendations in dupont-ipv6-rfc3041harmful.
