it's a very important concept, but it's a far cry from having a (redundant) gage and introducing it into the scanning pattern. Air speed is generally a very good indicator of how far you're from stall, unless you're in the army doing crazy attitudes very close to the ground. I'm pretty sure that small aerobatic planes don't have an angle of attack indicator, while the pilot would know everything there is to know about attitude control, having a number is not useful.
