Yes.
It may be worth noting that the "requirements" you're talking about
were very deliberately published in a document which professes to
contain "goals" and was intended to avoid any mention of the "r" word
(although I see we missed one in the title of section 3.2 :-)
The draft that led to RFC 3582 was originally a requirements
document. As you say, there was no confidence that there would be any
proposals which would meet all the items in the document if they had
been wrapped in MUSTs and SHOULDs. As the abstract says:
This document outlines a set of goals for proposed new IPv6 site-
multihoming architectures. It is recognised that this set of goals
is ambitious and that some goals may conflict with others. The
solution or solutions adopted may only be able to satisfy some of
the
goals presented here.
