Exam, all those things you mention are pilot induced or involve pilot decisions. Those issues will always be present. None of the them involve mechanical failure of components.
Adding a pile of mechanical parts of unknown quality in the form of a prosthetic bolted to the yoke adds a whole new layer of failure possibilities on top of the pilot induced issues you mentioned. Especially mechanical failures during the landing flare, when there's only a few seconds available and when most of the yoke inputs occur. How often do FO's practice recovering the aircraft and finishing the flare from prosthetic arm failure 2 to 3 seconds before touchdown.
( I admire this pilot and his flying skills, he deserves his medical. I'd fly with him every day as long as the mechanical arm they give him is reliable and airworthy. His arm needs a separate "medical", only from engineers and not doctors.)
