I don't follow your qualms about combining the two effects. We are simply
referring kinematic quantities to a moving origin and a changing coordinate

development of R = Ro + r ?

Well, my qualm is that I haven't yet seen an explicit definition of
R or Ro or r (or Ao or w), so it's hard for me to know whether I have
objections or not. I can guess what Ao and w mean separately, but
the relationship between them is not self-evident. Accelerations
and rotations do not generally commute.
