...(3) separating the medical profession into diagnosticians and surgeons to enable evaluation of surgeon performance.
During most of the Middle Ages, diagnosticians (physicians, etc...) were virtually always different people than surgeons (barbers, butchers, etc...). But yeah, that is a good thing, ceteris paribus (which the Middle Ages and now definitely are not).
Physicians and surgeons remain distint, but there is no particular reason a diagnosticician should also be a physician, since it is often a fine question whether a given problem needs surgical or chemical intervention.
