If it did have a single canonical URL, then the piece would be lost as the first one didn't make it to the front page in time.
I think this is not only a submission identity problem, it is also a ranking problem as many great submissions are missed that would easily make it to top 20 if they had the seed votes needed. (A parallel to startups not getting the seed funding they need :) ?) That's not to say it is a big problem, as HN has quality and in almost every case has the best on the front page.
