Obito, Madara and Hagoromo didn't use SPSM. This term only reffers to the mode Naruto used, indicated by the golden eyes with crossed pupils and no pigmentation around. Nothing in the description of the SMSM suggests it comes from the Tailed Beasts, it could be just enhanced by their chakra (forming a chakra cloak). Regarding Hagoromo's gift, the Yang Power Naruto received was necessary only for the Kaguya's SP-CT sealing. Aside from that, it doesn't seem to grant some other powers to its user, with the possible exception of Naruto's healing ability used on Guy/Kakashi. The same could be said for Sasuke's Yin Power, with its possible exception of influencing Sasuke's Chidori (its colour becoming black).
