Hagoromo brought Naruto and Co. back to their normal dimension using an advanced summoning jutsu, not Ameno.
As for other posters, I believe that:
(1) Hagoromo's ability to distribute Chakra was not tied to his Rinnegan; it's more similar to what Naruto did when he distributed Chakra to the Shinobi Alliance; and
(2) Kaguya's advanced Space/Time is not simply a Rinnegan Jutsu; it's a Shar-Rinnegan jutsu. She can't really be classified as a simple Rinnegan user.
I agree, however, that Sasuke's Ameno was his own, unique jutsu, just as Madara's Limbo was his own.
