It's telling you the GA speed (or approach speed) is too slow to permit the GA to be conducted with an acceptable margin to the stall.
This would be true on almost any procedure if you tried to do an EO missed at the MAPt...
That is what no one wants to hear, but alas...it is true.
You pilots thinks about this...you are at flaps 30 or 40 on final, near 140kts...and you lose an engine....
while you are trying to turn this bird upwards,
retract flaps, feather throttle, and retract gear...
now...think about all of the things you have to do...
and build that into an automated procedure...
assuming weights, temperatures, and engine performance...
