No, a contribution only warrants scholarly authorship when it is a significant intellectual contribution to the topic of the manuscript. Short of that threshold

No, a contribution only warrants scholarly authorship when it is a significant intellectual contribution to the topic of the manuscript. Short of that threshold, it appears in the acknowledgements; the acknowledgments is attribution for the work. As geebee pointed out, current practice may not be enough to acknowledge the role of technicians, core facilities, etc. in research and the issue is ripe for discussion. Nevertheless, I don't think that changes the meaning of scholarly authorship.
