Obviously it's bad practise to use flaps to popping them up and down like a drag control! Maybe it's having such a long history flying light twins where drag can be an enemy that I will only add drag when needed!
But here we are looking at an engine failure in a light single! Again drag should be only added when you need it and full flap when assured of a landing!
But pilots get it wrong sadly and lateral thinking in that situation should mean a pilot considers that extra drag and gets rid of it better that than to continue a speed glide profile into trees short of your landing spot!
I would not recommend the use of flaps in that manner in normal circumstances but would encourage pilots to be aware of that drag in emergencies
