Lol. It's totally going to be allowed this year...
@Cecil, just read the Motorsport article on rules for 2021 and it being banned:

A new Article 10.5 of F1's Technical Regulations states: "The re-alignment of the steered wheels, as defined by the position of the inboard attachment of the relevant suspensions members that remain a fixed distance from each other, must be uniquely defined by a monotonic function of the rotational position of a single steering wheel."
I think I'm coming around to it. It really is no different than changing the brake bias, through the steering wheel. That changes how the car will rotate through a corner as a result of the change. The changes to aero + suspension will change with the toe as a result of changing the steering angle of each wheel.
