I was more interested in this:
On the strategic map, many barbarian tribes have the "Hording" ability. This allows them to pack up an existing settlement and move the whole thing to another province.
Now currently, the one settlement a province concept makes such a thing impossible, so could this mean a separation of the two which would finally allow the representation of more settlements without having to cram the map with provinces?

Possibly, however, this is just going to be a spin on forts/watchtowers by providing a new brand of 'barbarian villages'.
