Careful, go-around from
minimum flight idle is not a cert requirement but 8 seconds from 'approach idle' (or whatever idle you get with the aircraft in a normal landing configuration) is a cert requirement and is most definitely demonstrated during cert.
As others have noted, with the flaps in landing the thrust needed to maintain airspeed is well above approach idle. We had a FADEC s/w error on a Boeing installations ~20 years ago that resulted in "approach" idle not being selected with the flaps in landing - the scary part was that apparently this error existed for over a year before anyone noticed because the thrust required with landing flaps was so much higher than idle.
