I don't think it's really fair to declare Arkham Unhinged non-canon just because of the issues with Arkham Knight prequels. Yes, the Arkham Knight prequel comics seem to contradict the games but that's on them, not Unhinged.

Besides, Derek Fridolfs, the author of Unhinged an End Game said in his blog: "both Unhinged and End Game get read, notes provided, suggestions made, changes enacted, all going through Rocksteady and DC before they're approved to get made."
