> / The concern I have with continuing to use an incorrect term, even though it might be fairly commonly used, is that the longer it is used, the longer it can cause confusion or error, and the longer it encourages the use of the inaccurate term.

"Unnumbered interface" is well established in the IPv4 world, and I
see no reason to believe that this document will change that fact.

> / Another point of confusion would be that in IPv4, unnumbered links are usually only serial point-to-point links between routers, meaning that hosts can't physically be attached to the link, where as any type of link can be an IPv6 "unnumbered" link, so hosts may be physically attached to the link if the link-layer is multi-access.

Strongly disagree about the IPv4 part. There is *large* deployment
of unnumbered links for end hosts in service provider environments -
for instance DHCP scenarios with one large DHCP pool being used for
thousands of unnumbered subinterfaces. I work for one such service
