The Jim Hall Chaparral was, I think, the first race car to use a movable rear wing. One iteration used air pressure from the front wing to activate the angle on the rear wing. The FIA didn’t like this, so outlawed it before it could be tried in F1, though they did allow a car with a big old fan on the back for a couple of races. How could that not be movable aero?
In any case, no matter how things change, they remain the same. Jim Hall never did get to build a F1 car.
Iirc the way they got around the rules with the fan car was by directing more than 50% of the fan’s airflow into cooling, therefore the fan’s predominate use was for cooling and any aero advantages it gave was just an ‘unintended’ consequence.
Still moveable aero. At the risk of going off subject, that car was originally designed to have surface mount radiators. When it was found that bad math had been used and this was impossible, Gordon Murray under a time crunch, put the fan on. But, he knew full well what it would do to ground effects.
