So for anyone wondering "why don't you just try it?' ...
My concern was DJI's propensity for trying to take control whenever they possibly can and as it turns out my concern was well founded because I just did try the latest DJI Go 4 version and the first thing that happened was that it locked the aircraft and required a forced firmware update! @#$%! Cycling power, etc. didn't help, in the locked state the aircraft cannot be flown until you install the current aircraft firmware. Nice. Typically DJI, and one of the many reasons I'm sticking with V01.03.0509.
Luckily there is a 3rd party utility called DUMLdore that will allow you to unlock the aircraft, and even more luckily it worked for me. Back on DJI GO 4 v4.0.7 now and obviously that's where I'll always be I guess. Just a note for anyone wondering the same thing.
