The airflow on top isn't the issue, the airflow underneath is what matters. Having the step is the best way to maximize the height of the front wing to allow more air to the rear of the car while still meeting new regulations. Exception being McLaren since their car has been designed around a low nose since 2009. From what I understand the step itself is relatively aerodynamically neutral.
