Whitegate/Al Zahbi is really the only area that they really should bother adding, but with a toggle to be able to hear those or not, only because...
On my server (dunno about anyone else's), it seems like Whitegate has become the "hub" for primarily JP-based shouts, whereas Jeuno has the majority of the EN-based ones. I see a LOT more moonspeak in the shouts in Whitegate. It's possible that there's some people who would rather tune those shouts out.
