Hmm, not at all obvious to me what this distinction amounts to.  
Unlabelled *is* existentially quantified, to all semantic purposes.  
Unfortunately, RIF has muddied this water by putting in meaningless

There wasn't time. I'll tweet when Ive got the slides on that topic  
posted, hopefully soon. In brief: there are at least 4 distinct  
notions of same-but-not-sameAs Ive managed to identify so far, and Im  
sure there will be more. Bottom line: no single solution will work, so  
no RDF2 magic bullet. But Im sure we can do something useful.

+1 on everything else in your list.
