Really? I've never seen the same minor faction control more than one region before.
I'd rather call them "minor factions" or "minor civilizations" so that they can also cover city-states, micronations, and the like, but otherwise I agree. Of course, I foresee this inevitably turning into a "What is a planet?"-style debate.
I saw multi-region Minor Factions in one of the early Open Devs, but not in the latest Victor Open Dev, so they may have modified that. In any case, the fact that Minor Factions can be aggressively hostile or 'peaceful', can trade (the option is in the UI, although in Victor I never saw them exploit any of their resources for trading), can be 'patronized' and rent out their units, all indicate that both games are aiming in the same direction with City States/Minor Factions.
What's left, IMHO, is to integrate the Tribal Huts and Barbarian Camps more thoroughly into the system to provide a range of Human Background to most of the tiles on the map: not necessarily all politically coherent enough to form a 'state' of any size, but potentially able to affect your settlement in the area, your trade routes, and even provide some bonuses (think Tribal Hut 'goodies' from a wider variety of sources that stay on the map afterwards)
