As for this, I made another proposal in a reply to Margaret.

I think ::/3 (except ::/128) should be treated as global, in terms of
*IPv6* scoping architecture.
(The address selection draft (by Rich Draves) treats (e.g.)
::ffff:10.1.1.1 as site-local, but, in my understanding, the main
purpose of this is to compare IPv4 addresses and IPv6 addresses in the
destination address ordering in terms of scoping. Thus, I don't think
the definition in the scoping arch draft contradicts with the
definition in the address selection draft.)

Honestly, I'm not so fascinated by this trick in API, but anyway, this
kind of API extension is out of scope of the architecture draft.
