This ticket is a result of investigations into T403008, T429366

Community-created Module code is inefficiently transcluding Wikidata entities, causing a much higher-than-necessary subscription.
We can try to mitigate this by pointing out common mistakes, best practices, tips and publish to Module writers, Tech News.

RecentChanges table optimization notes / investigation findings

Task:

1. Create a Project home page
2. Work with ENG to define the best practices
3. Identify and contact problematic Modules / their creators and maintainers
   • Explain the problem and see if they can provide an optimised code version
