I can think of a few places with GA alts of 1,500 feet or so AGL, so this is a real issue at those places. I have had a very new FO do his first GA at one of them because of a screwed up ATC instruction, so it was a real surprise (with such clear wx and runway) and he pressed TOGA. I had to pull the thrust back pretty sharply to prevent a flap speed excedence as he recognised the need to continue descending and kept the attitude steady, but forgot the thrust increase was so large for the attitude...
For clarity's sake, pressing APP again after it engages will not disengage the mode - it is one of a few modes that locks in, and this is indicated by the button's lights extinguishing on engagement; the light is only on when armed, and the mode can be deselected in that condition.
