I don't know about anybody else.....but i'm holding onto the thrust levers as i'm starting the flare...and if the speed protection is overly sensitive (as it is on some aircraft) and the A/T drops from arm in to MCP Speed when i'm at 20' i'm not going to let it move the thrust levers forwards..!
I think the benefit of having A/T go-around available is an advantage. Otherwise our SOPs mandate a Full energy G/A with manual thrust. Try doing that at Amsterdam with a level off of 1500'.....and think of the workload you potentially create for yourself and your colleague in the other seat.
