@UltimaDude, yeah, basically, it was useless, maybe, aside from the fact that Sasuke was officially tasked to investigate 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 found Kaguya's scroll and clashed with Kin/Momo in the ice dimension, i.e. got a promising intel on the threat and came into the direct contact with it. And in the case of Boruto, even his doujutsu powers don't seem to help, they just let Sasuke know what happened.
