Let's get into reality. Is flying a manual approach in airbus FBW normal or most alternate laws an evidence of extra ordinary skill? You just put the pitch and bank where you want it and it stays there. Set thrust at average setting and it will keep speed around the desired. Just keep speed in your scan.
No, it is not an extraordinary skill, but a necessary skill for every pilot. If you have that skill it means you have a good instrument scan and a natural understanding of the basics of flying like appropriate pitch, power, roll rates, spool up time etc.
As with every skill, most people need regular practice, and more practice improves the skill up to a certain point where the improvement flattens out. Asiana in SFO and Turkish in AMS did not have the instrument scan and impacted badly.
