While flying with the Game Master camera the Game Master is not able to hear the players on proximity, nor speak to them from the camera viewpoint. This is rather inconvenient as the GM cannot hear what are the players plans or simply take in their fun. The GM also cannot speak on proximity in the viewpoint of the camera which would greatly increase the ease of speaking as an AI without having to assume control of the AI.
It would also be pretty cool to be able to switch the "proximity chat source" from the last assumed character to camera at will, tho that's not that important.
