Change Details

**Feature summary** (what you would like to be able to do and where): T430759 reminded me that, while I sort of solved this issue with https://ru.wikipedia.org/wiki/Модуль:RedirectChecker for Russian Wikipedia, we should resolve it on MediaWiki level since any such solution could end up breaking from software changes. So here’s the basic proposition: there should be a MediaWiki tracking category, probably populated in all projects unless they explicitly disable it, that checks redirect pages that link to sections/anchors for whether an anchor exists on that page. Essentially it would need to check against HTML `id`s in the rendered page content since that’s the only reliable indicator of a link leading to a (likely) correct location. In an even more ideal scenario, there should be a customisable MediaWiki message that would be displayed on the redirect page in this case if a community desires that. While similar to {T395298}, this is broader in scope. **Benefits** (why should this be implemented?): 1. Link rot can be solved by editors more efficiently. 2. Modules like https://ru.wikipedia.org/wiki/Модуль:RedirectChecker or bots for tagging such pages are no longer required. 3. Wikimedia projects get a bit better for readers.
