Both are from the same R3 space, right ?

And we can add them together :
  Vector speed, position;
   position += time * speed;

I vote for Jim`s approach.

If a transform is { M3x3 + Translate }, them
  - transformPoint (normal transform) would be { P*M3x3 + Translate }
  - transformVector (delta transform) would be { P*M3x3 }
