If someone forgets to update both tags and they conflict with each other, please talk to them and try to figure out what they were attempting to do, and help them finish the job. I've added an issue on the Name Suggestion Index repository to hopefully make it less complicated to keep these tags out of conflict. https://github.com/osmlab/name-suggestion-index/issues/7857

Plus, data consumers can deduce much more information from `operator:wikidata` than from `operator`. If, for example, I want a renderer that displays the reporting marks of railroads, I can determine that by checking the statements in the Wikidata item attached to it.
