I comepletely agree Sherwood. However, the aero reduction the FIA is talking about is aero equal to 10% of todays aero (not a 10% reduction) That will be tough to make up for with all the limits to wing size and height, along with no more barge-boards or little flip-up all over the chassis. So it will take the teams some time to gain back what the FIA is proposing to take away.
"Evolution will always find a way" and few things are evolving as fast as F1 cars.
Oh and for brakes, those will be FIA provided as well
