Now that I've had some more time, I would say yes. At least as Gr3 cars are concerned. Haven't driven a whole bunch of others at this point but the Gr3 class is already too slow since the last time PD Nerf'ed the whole class and now they've done it again. Add to that the physics update which makes the cars that much easier to drive. Used to be about finesse and now it's just brute force. Thrown the car in, slam on the brakes, crank the wheel, and use the throttle like a binary switch, the car will respond.
It just doesn't make sense while exiting a turn the car starts to understeer.... the solution is just add more steering input. That's not how it works. If the car is understeering the fronts have started losing grip, adding more steering input would make them lose more grip not give them grip. It's the same thing under braking. Previously if you braked too late you went a bit wide and had to deal with it; now, you can crank the wheel towards the apex and the car turns.
I think the new updates have closed the skill gap and turned the race cars more arcadey than they were before.
I also love how they drop this set of updates before the North American GTWS. The European and Asian drivers didn't have to relearn how to drive their cars and get a huge BoP update right in the middle of their season. Imagine picking and qualifying in a competitive car and at the flick of the wrist within PD now it sucks. I know some of the NA drivers are less than pleased.
