Thus far I haven't had any practical need for this... so, again, I
would go back to the question about viable, non-theoretical use cases.

"All of them" becomes impractical for the reasons I've already given,
particularly without clearly defined, viable, non-theoretical use

That said, here's a compromise: Let's expand the uniqueness constraint
to include anchor, hreflang and type. Doing so ought to cover the vast
overwhelming majority of the possibly viable use cases. I can also say
that the server MUST consider the remaining target attributes to be
significant in that, *if* the server chooses to surface those links in
some representable manner, the most recently received values for those
MUST be included. Is that better?

(btw, getting back to your earlier question about the anchor
attribute, I had honestly completely forgotten about the anchor target
attribute! I've never actually seen it used in any practical sense so
it had completely slipped my mind... to answer that particular
question, yes, the server MUST consider the anchor attribute as being
significant. I'll add a few more examples)
