Why do you say its weasley-worded? I take this as a strong SHOULD. I
imagine that a single purpose IPv6, like a sensor may, in fact, have a
single IP address. Some text clarification may be OK, though, how about
adding to the first paragraph the following text:
It is expected that most implementations will indeed support this, as
since the number of addresses a node will have is more of an
operational issue.
