BARKINGMAD - it's not that we aren't capable, it's just not a manoeuvre discussed or prepared for. In our case, we disconnected and levelled off, followed by a bit of button pushing and confusion before FDs were recycled and we got George back into the game.
If training departments don't discuss these scenarios or throw them in, people will only learn when they find it on the line. An awareness that whatever is set in the MCP and whatever your position relative to that altitude, that hitting TOGA always gives you a climb command is also not always present. If you get trigger-happy with TOGA the moment someone says go-around you can find yourself in trouble. Our training department now teaches "take a deep breath" for unanticipated go arounds above minima.
