In the course of cleaning up the dom/sub tags I've run into some posts that are tagged dom_turn_sub or sub_turn_dom based either on a story in description, or based on earlier scenes that establish a character as a dom or sub. I've removed the tags from those posts since they violate TWYS, but this shows there is a demand for using external information to support role_reversal kinks.
Under normal circumstances I'd say this seems like too narrow of a use case to justify lore tags, but we do have power_bottom_(lore) and service_top_(lore) tags, which are even more specific.
What do people think?
