I in princeiple I agree, but considereing that `vectorize(disable) vectorize_width(scalable)` is being rejected, where is the ambiguity? Is `vectorize_width(1) vectorize_width(scalable)` the issue? I don't think that it should be interpreted as `vectorize_width(1, scalable)`, it is just conflicting information for the same setting.
