It's all that simple
 * And against whom he's supposed to use them? We have an era of peace and prosperity. Only Toneri was suitable opponent, but I think it's clear that Naruto's SPSM design was created after The Last movie had came out, so it had no chance to show up these, so did the SPSM powers too. Then the only villains Naruto fought against were Shin and Momoshiki, but the former wasn't that a threat to use any advanced powers on him, and against the latter any ninjutsu was useless.
 * Again, Naruto's speaken to the TB when their power was necessary. As I said before, in all the crucial post-FSWW fights Naruto either didn't need their powers or was somehow restricted. But since Hagoromo wanted for Naruto to became a link between all the TB, it's also clear he still can speak to them anyway.
