> IMO RFC 6164 although being very authoritative and direct about use of /127 (from the same /64) on each p2p link is not giving us any insight into other current (or future) reserved addresses that were explained in more detail in RFC 5375 so in doing that RFC 6164 is raising doubts in our minds about using /127 (from the same /64) for p2p router links and also there is no talk in RFC 6164 about use of /128 loopbacks and what cautions are needed there - whereas we saw that in RFC 5375 (although informational only) there was a more comprehensive discussion around use of shorter length prefixes for p2p links and loopbacks

*You* may feel that RFC 6164 is raising doubt. I don't. I'm glad to see
an RFC that fills a needed hole, and clearly describes something which
is already used by service providers (including my employer).
