Mercedes DAS returned?
Discussion
There was a bit of chatter around George Russel's car on Twitter last weekend (and surprisingly only George's) about a couple of bits of footage that appears to show the steering column moving.
It's not as obvious as the old DAS system but in amongst me and some of my F1 mates having blown the footage up, the steering column is indeed moving.

This is only one post of a few different ones although not being official F1 these can be taken down.
I know the anti-dive geometry is baked in but the front geometry 100% moves as well. The easy way to dismiss it is of course George moves at the same time the column does but he's only strapped in, in my experience the steering column has zero flex in it as intended so what is this?

You can also see the movement of the wheels on the other cars.... RB, Ferrari, Mclaren (albeit no steering wheel movement)
The Mercedes anti-dive looks much the same as the other cars to me. There is also no rule against using longitudinal movement of the steering wheel to adjust something, they just can't use it to adjust the toe. However I suspect they've just engineered the steering column to be as light as possible and Russell puts an abnormal amount of force on the wheel when braking which causes it to flex slightly.

The new regulation language is:
10.4.2 “The re-alignment of the steered wheels must be uniquely defined by a monotonic function of the rotation of a single steering wheel about a single axis. Furthermore, the inboard attachment points of the suspensions members connected to the steering system must remain a fixed distance from each other and can only translate in the direction normal to the car centre plane.”
It could just be play in the system under load, or perhaps used for something different, but it definitely can’t re-align the front wheels or suspension in any way.

It's badly doctored footage, watch the add logo's on the Halo.10.4.2 “The re-alignment of the steered wheels must be uniquely defined by a monotonic function of the rotation of a single steering wheel about a single axis.
