    I'm not sure what world I live in ..... and I don't have any super optical technical knowledge ........ but you always come up with theories, (which could be technically right no doubt)  ..... that I struggle to align with my own experiences. 
Nikon has not a flawed system..... and as JoJu says ..... most of his lenses needed AFFT and the result is fine ...... so all I can conclude is these theories just don't apply themselves in any meaningful way to my shooting.
  If DSLRs didn't have AFFT I would have dumped them years ago!!

 JoJu, the Tamron has trouble at 600mm@ F6.3 to achieve focus on the outer corner points (D500) .... this is normal ....... not great, but normal.
