This is a question to ask Paizo - whether or not the Rage domain and similar things, which were all printed before Pathfinder Unchained, were supposed to be integrated into the Pathfinder Unchained material. Once they've published an answer as to how these should work, we'll implement their answer.
I think what will probably happen is that Paizo will publish a book in the player companion line, like Advanced Class Origins or Mythic Origins that covers all the corner cases like this and adds Golarion-specific material relating to Pathfinder Unchained.
Please do not add bug reports to unrelated threads - that means they're very easy to miss. Please use the links in this thread:
