I guess the clue of non-screwdrive support is in this text from Nikon:
"AE shooting is possible with approx. 360 types of lenses including AI NIKKOR and those released afterwards. Among them, a total of 94 types or more of AF-P, AF-S and AF-I lenses incorporating motors support AE/AF shooting. Depending on the position and movement of the subject, which affects lens drive, there are various difficulties when focusing. Aperture control may take time and continuous shooting speed may be slower with some lenses."
