This exact text is also present in RFC4291 section 2.5.1. As far as I know, this has been part of the IPv6 address architecture since 1998 (RFC2373). > Although I do not see a MUST in this sentence, it appears that the > proposed standard is mandating that all interface IDs be 64-bits long. > This is not a requirement in several RFCs listed below. As a result, I > believe that this requirement should be stricken from the document. That would be a no-op, since it's already required by RFC4291.
