With Venturi tunnels you don’t want the air pushed to the sides of the car, you want as much as possible fed into the tunnels. Imo barge boards would be counter productive if used with the 2021 Design.
The vanes at the front edge of the floor are quite aggressively cambered outwards too!

Correct me if I'm wrong, but I was under the impression those aggressive vanes were designed to create vortices to seal the sides of the tunnel and increase their effectiveness without resorting to moving skirts?
Air is quite full of itself, in an arrogant way, to understand air, you must also be full of yourself. Then and only then will you understand airflow, and why it's all based on being full of oneself. If you try to deny air the ability to be full of itself, it will lash out, and do everything in its power to once again be full of itself. It cannot be any other way. Air you see is a prima donna!
So when you see deflectors, they are causing air to not be full of itself, by pushing airflow out the sides of the car, you create a low pressure zone at the throat of the floor tunnels. Air being full of itself will instinctively try to fill the void left by the deflectors.
In other words the deflectors are there to encourage airflow through the floor tunnels because either side of the tunnels the pressure is higher than at the throat, and air will go to the place where it is less full of itself.
