This discussion was prompted by a remark of ignorant TRI. Windshear is a well researched subject and has established procedures. Any modifications from that is fraught with danger and definitely beyond the perview of a line pilot. Not changing configuration due to increase in drag/reduction in lift is an established procedure. That doesn't mean you just watch excess speed destroy flaps. Why won't you take care of it by converting speed into height because the higher altitude may take you out of wind shear itself. If it doesn't then when the trend arrow reverses again fly the FD again.
