> And, I said that if it were *truly* opaque to *all* examinations and references, then
there would only ever be *one* DUID type for all time. But, RFC8415 clearly shows
that multiple DUID types are defined and that new ones can be added through
future standards action.

Fred, the questions continue to be not about whether "other types of DUIDs can legitimately be defined in the future," but rather, why should an IPv6 address be used as some arbitrary node label, as opposed to using any of the DUID options already specified. Why insist on using IPv6 addresses for this purpose, in short?

By strange coincidence, I got a similar request a couple of weeks ago, to do the same sort of thing. Use an IP address as an arbitrary node label. I have to admit, I too resisted the idea.
