Depends on what you want. A lot of the interest in FPV is acro flight, not autonomous, so there isn't a lot of interest in improving that (at least for beta flight)
You act as if separate backhauls is a bad thong - I'm not sure that's self evident. Short range just seems wrong to me - RC transmitters outrage all of the current video tx systems, and in open air video tx is long enough that you run into problems with battery before anything else. The best video tx systems currently is proprietary (DJI).
Open source is good enough for what most people care about. An open source high quality video tx would be awesome, but obviously a significant engineering effort relative to everything else.
