I think there was a similar restriction when ground effects had limitations on sliding skirts.
When the advantages of wings was explored after 1967, many novel ideas were quickly tried. One great theoretical concept is to directly attach the wings to the suspension uprights, thus taking the load off the sprung mass. And of course, moveable aero devices have been tried too. The Chapparall Can-Am racer had a huge moveable rear wing, selectable by a driver's pedal. And the Mercedes GP Lemans of years gone by had a huge airbrake behind the driver. If you combine attaching the wings directly to the suspension uprights, and have them moveable, either by computer or driver preference, the theoretical advantages are huge. it would definitely lead to a much quicker racing car.
If we start to ingore and turn a blind eye to this basic concept, then engineers will make parts and wings that flex and contort, to give performance advantages. Yes, it could lead to a faster car, but it also leads us down the path of increasing risk, and less safety. This is a basic philosophy, and I personally believe it should be rigidly enforced.
But as they found out in the 60's, that wings and their attachments can be fragile, especially since a wing directly connected to the suspension uprights would be subject to every bump and ripple on the road surface. Mechanical failure is very possible, and that leads to the safety issue. So the FIA decided (and I personally agree) that in the interests of safety, wings have to be attached firmly to the body structure. And on that philosophy I agree. Wings and all downforce generating parts of the car must be attached to the body in a very firm manner, so that movement is almost totally eliminated. In the real world parts do vibrate and flex under load. But they should not be designed, or allowed to have flex built in.
