A taller rider is sitting more rearward of the bottom bracket than a shorter rider. To achieve the same weight distribution the chainstay would need to go back as well.

Yup.
My Thorn touring bikes have different chainstay lengths for different sizes, my Nomad Mk II came in 8 sizes, they had 4 chainstay lengths for the 8 sizes. And my Thorn Sherpa had 11 sizes, there were 4 different chainstay lengths for the 11 sizes. Both of those models are out of production.
But I am not aware of any other brands that do that.
