I do not believe that the D5/D500 is "broken." I believe that with the increase in AF points and AF speed they have simply made it more "hyperactive."
Interestingly, the D5/D500 is now behaving *more* like the description says it should: "Dynamic-area AF: In AF-C focus mode the camera will focus based on information from surrounding focus points if the subject briefly leaves the selected point."
There is also a note in the manual in regards to 3D/Auto not being available above f/5.6.
I have found 3D to be better than previous iterations, but not nearly "flawless." There are obviously other factors that affect how accurate it is. I have also used Auto to capture subjects that are almost impossible to acquire/track (chimney swifts).
