It is a breaking change, but not sure how widely and also C API is really best effort stable (meaning, we _try_ not to break it). I probably should have included a Module suffix on the original, and then this could have gone without. How many usages in the wild can you find of this call?

(Nit: ForOp suffix makes me think it's related to ForOp).
