Should TARGETED_DEVICE_FAMILY include iPad (2) for an iPhone-only app to properly support the foldable inner display?

Our app declares TARGETED_DEVICE_FAMILY = 1 (iPhone only), yet the unfolded inner display presents a .regular horizontal size class identical to iPad's, and our project also carries a leftover INFOPLIST_KEY_UISupportedInterfaceOrientations_iPad override. Does Apple recommend/require declaring iPad as a supported family for apps that want to support this device properly, or is "iPhone-only + regular size class" the intended long-term model?
