Comment:
> Perhaps this need could be met by improving ST_ClipByBox2D so that it
produces valid output geometry?
For this use case, `ST_ClipByBox2D` won't execute GEOS functions unless it
needs to (it has bbox shortcuts).
In any case, I do see the benefit of checking whether one of the input
geometries of ST_Interects/ST_Intersection is a box to add some shortcuts
(not exactly the same for both functions but still a benefit).
