DECSTBM doesn’t work because of our unicode half-block shenanigans. We’re squeezing two pixels into each terminal character, and so we want to be able to “scroll” in half-pixels; our scroll needs to turn lower half blocks into upper half blocks when we’re moving vertically. That operation just doesn’t exist.
