Add an option to the random articles query API to receive good or featured articles, as identified by Template:Good_article (Q5303) and Template:Featured_article (Q5626124) Category:Good articles (Q8536695) and Category:Featured articles (Q4387444) respectively.
It is understood that the availability of this feature would depend on whether a wiki has those templates categories linked to wikidata and if they actually use them on articles.
This would be used by the KaiOS-Wikipedia-app (and possibly others) to surface articles that are probably worth reading, as opposed to stubs about remote villages.
