It's an interesting point, but I suspect it's generally not taught that way, as when you have to do an unplanned go-around, you might lapse into your touch and go routine. Then by the time you are good enough where the workload is less of any issue, changing the flap settings becomes less of an issue.
I agree flapless into Netherthorpe isn't a problem, I don't know if I'd fancy turning that into a touch and go, but that could be me! (I usually put one stage down even for a Cross Wind as a bit of a compromise) - could be my turn to duck.
