Comparing #Wikipedia using blue, red and black links
One problem with "blue" links is homonymy. You write a subject in the same but they are not the same; John Doe is one example. Finding these issues, issues that are surprisingly common, can be done by a bot using the Wikidata identifiers for the linked articles.
When there is no article to link to, there is no implicit link to Wikidata. There are two options; we can fake a link by accepting the red or a "black" link as synonymous or we can link a red or a "black" link to Wikidata. The latter is precise and has additional benefits.
When all links are associated with Wikidata items, it is obvious what links in what language are missing or are additional. They are of interest because they may imply potential information to be added to articles or they may point to errors even vandalism. Another benefit is that it helps establish a baseline for a NPOV or neutral point of view without a need to understand the language.
