Clearly you have never left the US and are not familiar with the various forms of noise abatement procedures used worldwide. Google NADP2 (Proc B) and you'll understand most non-US carriers worldwide routinely accelerate and commence flap retraction at >800' (NADP2) or >1000' (Proc B) above 1000' AFE.
