I agree that it would be good to redesign it, but am not sure where to start. A bit of a tangent, but if you are thinking about re-designing this, then it may be worth considering ob-jupyter's implementation of async sessions [1]. In particular, I believe it leaves a marker [2] where it needs to insert the future result. I don't remember the details, e.g. how it keeps track of which marker is for which result. But it seems neat, and might work better for some cases such as appending/prepending results.
