GrowthExperiments includes a number of mostly-independent features (welcome survey, newcomer homepage, help panel, link recommendations, image recommendations), all of which can be disabled, enabled in stealth mode, or exposed as a user preference that defaults-on for some percentage of new users. This is tracked in https://www.mediawiki.org/wiki/Growth#Deployment_table manually, but that can get out of sync and in general the setup is accident-prone. It would be good to have an automated dashboard that reflects the actual state, is precise enough to be useful for QA-ing wiki configuration, and is accessible enough to be useful to non-engineers and the general public. (The ORES support checklist would be an example.)

Implementation-wise, GrowthExperiments could expose configuration via some API that uses the same internal primitives (HelpPanel::isHelpPanelEnabled() etc.) as the business logic, and a simple Toolforge tool could periodically query those APIs, cache the results, and render an overview. The cache could be a local file, or it could be a Commons tabular data file if we want a public audit log for free + easy ability to add notes manually.

This could be a part of T249987: Scale: GrowthExperiments wiki monitoring dashboard when that gets implemented.
