There is no focus priority setting for AF-C, just focus + release which just slows the framerate.


in the menu there is. It's called "focus" "focus + release" is a separate setting.


So there is, seems to be a change from D3/D700

Even f/2 and f/2.8 has very shallow dof at portrait distances. If the subject is static use AF-S, that way the camera is not trying to track with potentially focus jumping backwards and forwards slightly.
I'm using AF-C to compensate for slight movement of my hand...


The slight movement of your hand is probably smaller than the AF error

All this said, fast primes seem to not be particularly consistent in this scenario perhaps due to their lower contrast. 2.8 zooms seem much more consistent.

Possibly, but that doesn't stop others from getting great results with primes, not to mention it's necessary to use f2 and higher due to lighting sometimes.

People just delete teh oof frames. If you are shooting with such shallow dof it is a fact of life with phase detect af.
