That wind blows in and it thinks the car is going faster than it really is and starts adjusting the A/F ratio. Again I've done this on other cars and it makes it super annoying to drive and it bogs, hesitates ect under light throttle and in closed loop map setting. Under WOT open loop it was fine.

the MAF sensor does NOT expect anything related to any speed.

It is just a sensor that detect airflow by the mean of a heated wire.
if a wind blow too much on it , yeah that will cool down the heated wire which send a signal that is received by the ECU then adjust the AFR.

depending on the intake bent and location of the MAF sensor, yeah it might not be good at certain occasion.
