@UltimaDude, yeah, basically, it was useless, maybe, aside from the fact that Sasuke was officially tasked to the matter as a secret mission of his. Anything else didn't make a lot of difference, Kage were unable to do anything to the threat until it actually showed up. The only one who was able to do something is Sasuke, due to his doujutsu prowess and dimension-travelling powers. Technically, he could keep the matter for himself up until the moment he clashed with Kin/Momo in the ice dimension, i.e. came into the direct contact with the threat. And in the case of Boruto, even his doujutsu powers don't seem to help, they just let Sasuke know what happened.
