Recent observation of four-, six- and eight-particle cumulants with \"correct sign\" $c_2\\{4\\}<0, c_2\\{6\\}>0, c_2\\{8\\}<0$ and approximate equality of the inferred single-particle harmonic flow, $v_2\\{4\\}\\approx v_2\\{6\\}\\approx v_2\\{8\\}$, have been used as strong evidence for a collective emission of all soft particles produced in the collisions.
