If I understand your post correctly, I believe what you describe for the 3 is the way the S and X have always worked in that regard.
I had never heard of such a thing before. Note: I am not a car guy. I know extremely little about any cars other than those I've owned. I got the Roadster, not because it's a sports car, but because it's electric and I hate gasoline. I want the Model 3 because it's electric and will be more practical than the Roadster (a much as I love the Roadster).
And yes, when I remarked on it, my friend told me that the S and X and several other cars are like this.
