I mean, there is even stuff like linking to pages in PDF files... but I feel like it's another feature that's rarely used.
Maybe, in an ideal world, I could imagine an editing experience with a split screen editor with the article text and the references open at the same time. Right now, it does feel like references are an afterthought in the editing workflow.
Maybe I need to add a section (in bold, flashing red text?) reiterating that you need to read the citations and not rely on the content?
This recent example is awful, yes, but relied heavily on a Wikipedia project which has less strict referencing rules, and was consumed by people who didn't take the time to fact-check — we're about on par with Encyclopedia Britannica (ref: https://www.nature.com/articles/438900a)
