Some rather valid observations giumick! I would also tend to believe that per my interpretation of FAA PIC responsibilities it is that any and all configurations of an aircraft flown by a certified pilot are the final responsibility of the PIC. Now since almost all of us on this forum have little to no experience with making changes to flight critical firmware functions and parameters, beyond what DJI GO 4 enables, almost by default we must trust DJI to provide us highly reliable firmware. History has proven that this is not always the case. History would also indicate that DJI has proven to gotten better at meeting that threshold.
However if "the buck stops here" with the PIC, then we pilots are by default put in a position to accept that the factory provided hardware and flight control software from DJI are the safest configuration possible as presented in previous posts in this thread.
I believe that many of us might not see the DJI software as safe to fly with as their hardware is. In fact throughout all high technology applications involving microprocessor controlled hardware it is most often the software which fails, "has bugs", more frequently than hardware. In fact most hardware components usually have been exposed to rigorous testing which provides data that often predicts at how many cycles of use or hours of operation this particular component will likely fail.
So why so many posts claiming any mod of flight control software will automatically make the aircraft less reliable? In fact any mod of flight control software only affects the ability of the PIC to interact with the aircraft. However whether this theoretical mod would improve or degrade the PIC's ability to safely control the aircraft is not really a pertinent question of breaking warranty or insurance policies. Why? Because all pre-flight inspections and care of the aircraft in addition to flight time, landing and post flight inspections are the full responsibility of the PIC.
Therefore any hardware or software mod performed by the PIC should only be in the interest of improved safe operation of the aircraft. If this is true then each of us have the responsibility to fly the safest aircraft possible and this is again based on the professional wisdom and experience of the PIC. So to mod or not to mod becomes a personal decision.
I am not a lawyer nor am I trying to "beat a dead horse to death", but after looking at specific portions in the part 107 law relative to flight safety, my interpretation is that we pilots are ultimately more responsible than DJI to perform safe flight missions. So DJI is, as per FAA guidelines, not responsible for providing safe, reliable flight control software. However we are responsible for safely flying what DJI sells us. I hope those watching this thread choose to let me know if I am off track here.
And yes this post might have not been exactly in line with the OP, but as a related branch off the OP, which was to bash a particular parameter mod app, it must be understood that any flight parameter mod whether by NLD, GO 4 or using any other means is still the responsibility of the PIC.

. On another occasion I had someone in sales adamant their computer had a major problem because it kept rebooting all the time. Every time we took it in for testing it worked perfectly, nor would it reboot if we tested it at her desk. Eventually we sat and watched her working on it for an hour or so, to discover that she was accidentally gently kicking the reset button on the front with her pointy shoes when she started swivelling her chair around
