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.
Quadtree-based image compression formats and level-of-detail systems all work this way. Satellite imagery, terrain rendering, and geographic information systems use quadtree decomposition to serve data at varying resolutions: zoomed out, you see large coarse blocks; zoomed in, you see fine-grained tiles. The same principle extends to three dimensions (octrees) for volume rendering and 3D spatial indexing.
