You won’t even place in a STOL competition flying POH defined approach profiles at POH speeds unless you have some sort of super-STOL aircraft. So yes, it’s going to happen as long as STOL competitions are a thing because the margin for error is essentially zero. A lapse of concentration or a swing of the variable wind and you’re going to have a stall when you’re flying basically as close to critical AoA as possible as a matter of course.
