I see your point I really do BUT this feature has never really caused me a problem and I own lots of DJI drones.
I kind of like the fact that DJI will not help anyone but me if questions about my drone arise. DJI has always maintained contact...
I walked a path much tighter than what you are describing yesterday with no view of the sky at all and places where I had to duck under branches. My Mini 4 Pro managed really well, better than I would have flown it.
It's much easier for everyone involved when the previous owner unlocks the drone. You seem to have convinced yourself otherwise, but that reasoning doesn't really hold up.
