The Growth team is planning to deploy its features to 100 wikis: T247507: Scale: deploy Growth features to 100 wikis.
Right now, deployment of suggested edits requires MediaWiki:NewcomerTasks.json to be pre-populated by the growth team (right now, only @Tgr has the permissions to do so). How are we going to handle this when we deploy to multiple wikis at once? Should we keep some sane defaults in the extensions's code?
