Shima and Fukasaku weren't listed as Sage Mode users in databook 3 though. That's why there's debate about whether only humans can use it. Gamakichi or Hakuja Sennin being listed would clear it up, I suppose. Otherwise we're stuck guessing whether they count or not.

@Reliops Hagoromo is listed with kekkei mora. In fact, he and Kaguya are the only ones. I'm pretty sure Kaguya's Expansion TSB has its own entry, so that may shed some light on things.
