The newest generations of medium format cameras are becoming more capable though. Hasselblad for example measure and compensate for the distance affected by centring the focus point and then reframing. The newest S (Typ 007) includes predictive focusing, etc. And yes that was how I was taught with SLRs too (and spot metering control). The model and photog obviously work together to maintain the working distance and for full length or 3/4 length with a standard lens the DoF is quite sufficient to allow movement with feet position unchanged. One of the reasons for typically working stopped down like that is to help ensure front to back sharpness of the subject there. The more critical example I quoted was with a tightly framed headshot for example. For portraits such as I have showed samples from you can bet that each was individually carefully focused on the near eye.
