Not seen it suggested before, but I know languages has been talked about. Given there are options to remove peoples hearing and tongues as well as PC's who have opted for that sort of RP.
Not to mention the cool things that can be done with hand gestures that people do not understand.
Curious if it could be added as another language to learn, and be considered as a silent form of communication. Could be very cool for all sorts of things.
