Good observation!
Years ago I shared a Japanese-built STOL aircraft which employed wing suction to allow very large angle of attack, high-drag, high-lift flight. That plane had 5- jet engines. One of those five engines was specifically tasked with powering the necessary suction air mover for the wings.
Georgia Tech is the most recent university to study blown and suction slots. So far, the takeaway, is, that it takes more power to run the fan, than is recovered from the flow attachment produced.
