i.points3 and i.rectify3 doesnt uses standard lib. So adding API style code
which can be used by i.point3 and i.rectify3 is what you are saying. Am I
correct?

i.ortho.photo uses i.ortho.photo/libes right?

so merging both libs will provide an API which any grass imagery module can
share right?

This part is not clear to me at all
