In my opinion, it's like when an expedition to an 8K is at a few meters of the top of the mountain and it makes the news. They are not there yet, but it can be interesting to follow the last steps, even although it is perfectly possible that they do not make it at the end. And from a more academic point of view, although this is not a new discovery, it can be an interesting line of research. If they have used all the available data and they could only get sigma 3, I think it makes sense to publish what you got in order to justify spending your time trying to either make that a five or discard the hypothesis.
