This would allow to render 4 or 16 times more triangles as draw calls would be reduced by the same amount and striding and viewport clipping would take care of the rest
Edit: rather perhaps use texture2DArrays here too, instead of megatiles, but neighboring would become pretty complex.
Moreover, without sparse texture extension, larger virtual dem tiles at the edge of a selection would possibly take a lot more space
