The minimum radius rule was very necessary. It worked well, just as it works well in the 2022-present regulations.
In the modern era, teams will put literally hundreds of winglet/strakes/fins anywhere there is a free legality box, hence why there almost no free areas in the 2022-on regulations at all. (Apart from small sections right next to the chassis sides and around the cockpit.)
If you had maintained the 2006-type rules to present, instead of just the bargeboards and under & over the nose having hundreds of vortex shedding edges,
the whole car would have that all over it. All those single or single slotted winglets on the 2008 would almost certainly each turn into 5, 10, 20 or more elements as we saw with the bargeboards and other fins. The cost to manufacture the cars would be outrageous and frankly they would look ridiculous.

A 2006 formula with venturi tunnels would have been

they've already gone back to center loaded FWs in '22).
The only thing stopping front wings with 50 elements in 2006 was time, there was nothing in the rules stopping it...
McLaren, Ferrari, Williams and Toyota already had double layer front wings in 2008, as a precursor to the elaborate front wings of 2011 and onwards. McLaren's upper front wing had already gain a slot by the end of 2008 and you can expect it would probably have gained 20 slots by 2022...
I maintain that the minimum radius rule was a good idea, as it made the sidepods look much neater, as the sidepods still do to this day.
Obviously creating the Y250 vortex and making the rear wings narrow was a mistake, however.
