It is a curse when the topic is no longer popular. No longer is there an interest to maintain the information, new publications are not integrated in what used to be a neutral point of view.
In the references section of an article you find the underpinnings of what is stated in an article. It may be newspaper articles or science papers. Both newspapers and science have a hard time attracting attention and this endangers the availability of quality sources for future updates.
In Scholia information is continuously updated about the latest papers by authors and or about subjects. As time goes by, papers become available dated later than the latest reference. When such papers are clearly marked, it is an invitation for the Wikipedia community to revisit a subject and learn if what was a neutral point of view survives as such vis a vis the latest information.
Every subject should have its own Scholia.
