Problem: Currently the only way to get notified if someone added Example wikilink to another article is to have created Example themselves. Similarly, automatic notifications for deletions/redirections of an article are only sent to the creator, despite multiple people having vested interests. This is the current behaviour on English Wikipedia and possibly other wikis too.
Proposed solution: The simplest solution would be a bundled "co-creator/virtual creator" flag that someone can watch to, akin to "watching".
Who would benefit: Anyone deeply interested in specific articles on a similar if not greater level as the initial article creator
