I doubt we would ever see any other a/c instrument settings, or flap settings. It would mean that that even more information (throttle, RPM, acceleration readings, Fuel loads, trim settings etc etc) from other players front-ends would have to be sent to all other players who are in visible range. Some info i assume is already sent like heading, aileron, rudder, elevator inputs, flap settings etc. To add more information would mean more information has to be packaged up and sent and managed, and then unpackaged etc and processed at the other ends and would lead to increased traffic that the server has to forward as well as increasing the volume of traffic coming down the wire to you.
What I'm getting at, is it may take more effort and waste more resources than its really worth.
What i would like to see in the film viewer is a truly independently positional camera - the ability to program the camera position in terms of X, Y, Z, and Time, rather than having it relatively fixed to the aircraft you have selected. So you can effectively program a chase-camera which you can fly anywhere in the virtual world and then have the camera able to pan, tilt etc from that position. Would make for endless cinematographic possibilities.
