Feature summary:
Surfacing the WikiProject through wg config variables on PageAssessments.
Use case(s):
CentralNotice is a viable use case, though there are probably many others. It is unfortunately not possible to surface WikiProjects on enwiki or those with a similar setup, as the relevant wikiproject categories are on the talk page. And the mainspace categories are not organized enough to do something meaningful on this front without a list of hundreds or thousands of subcategories.
Benefits:
I think CentralNotice use could be of high utility in reaching out to particular interest areas and demographic groups, especially underrespresented ones. And I believe it has great potential for both virtual and in-person events, and potentially also for fundraising applications.
