I guess, it means that we can't add pyramid to krita/image. Right?

There is a start variant of pyramid based on paint devices in
attachment. What do you think of it?

PS:
I decided not to introduce a special paint device as in such a case we
won't be able to use KisImage's projection as a zoom-level-1 image.
