I don't think my syntax suggestion would change that much, other than to make it a bit simpler. It would be:

apply motion (= motion translation)
apply translate
apply rotate (including calculated rotation based on earlier motion translation)
apply scale
apply transform

You might get somewhat odd results by combining motion translation with translate(), I guess, but the solution is for authors to not do that, or to do it with eyes wide open. It would be different from what is expected in current motion-path spec, but not necessarily bad.
