I'd also like to see a more detailed motivation for this. And, if it is useful, then that would make 3 operations that have special case pairwise moving window variants (subtract, floor_divide, true_divide). 3 is a lot of special cases. Should there instead be a generic mechanism for doing this for arbitrary binary operations?
