What's the relevance of Efimov physics?

Is it something unexpected?Why universality in cold atomic gases is important?What researches are looking for?Can this be useful for topological quantum computers?

Can we expect a whole myriad of these states?

Edit: It's also worth noting, in retrospect, that there exists an analogous phenomenon in 4-body physics: recently it was noticed that for every Efimov trimer, there are two corresponding tetramers. I think some people conjecture that there are similar any $N>2$-body Efimov states, which seems to me still rather different from the logic of the paper in the original question.
