There's probably no point in going much faster for most control systems of physical devices of the sizes we're talking about. The actual response time of actuators and time to see the results of changes on sensors is much longer. Think the time required to actually adjust the throttle or gimbal a huge rocket engine, and then the time required to see an acceleration change as a result of that. They probably use higher rates for stuff like measuring combustion dynamics during ground tests of the engines in development. If anything is wrong there, they'll probably seek to correct it via mechanical or fluid dynamics adjustments of the system itself, since active control systems could probably never react fast enough anyways.
