OK, so I typically use DOIs in my bibliographies, although I seem to be in the minority for now. What next? You have to find the exact name of the author that changed and edit it. Let's say you do so (not a trivial undertaking since references do not come in a standardized format even if the DOIs do; by the way, arXiv doesn't understand bibtex). Now my paper says "Merton and Fox observed in [5] that...", and you know that Fox (one of the authors of the [5]) became Wolf. Will you change my text to "Merton and Wolf observed in [5] that..."? How can you tell that this particular "Fox" is a surname rather than the animal? What about acknowledgments, which come with no DOI or ORCID?
