GTK4 moved rendering to GPU and gave up on RGB subpixel rendering. I've heard, that this GPU-centric decision made it impractical to continue with RGB subpixel rendering. The article shows it is possible. So perhaps, the reason for GTK was another one or the presented solution would have disadvantages or just not integrate in the stack...
Cosmic Text (Cosmic DE) might do this on the GPU via swash. It has subpixel rendering.
