FYI, the 1.42 branch point is in a matter of hours; it doesn't appear that this will be done by then?

The stable policy grace period is now closed, so any code from now on that has not been marked as @internal or @private should be considered stable per the frontend stable policy.

For GrowthExperiments and GuidedTour, the following APIs (and all public methods associated with these objects) can now be considered stable for use in extensions and gadgets (and are subject to the deprecation policy):

• mw.libs.ge
• mw.guidedTour
• mw.libs.guiders

Hooks:

• growthExperiments.contextItem.openHelpPanel'
• helpPanel.hideCta
• ext.growthExperiments.HelpPanel
• growthExperiments.mobileHomepageOverlayHtmlLoaded
• growthExperiments.helpPanelQuestionPosted
• growthExperiments.mobileOverlayClosed.*
• growthExperiments.mobileOverlayClosed.suggested-edits
• growthExperiments.mobileHomepageSummaryHtmlLoaded.suggested-edits
• growthExperiments.contextItem.saveArticle
• growthExperiments.contextItem.openHelpPanel
• growthExperiments.structuredTask.onboardingCompleted
• growthExperiments.structuredTask.showOnboardingIfNeeded
• growthExperiments.suggestionAcceptanceChange
• growthExperiments.imageSuggestions.onImageCaptionReady
• growthExperiments.structuredTask.onboardingCompleted
• growthExperiments.structuredTask.showOnboardingIfNeeded
• growthExperiments.onAnnotationClicked
• growthExperiments.suggestionAcceptanceChange

If this is not acceptable please comment in the next 7 days so we have a record of the intent to change this, otherwise we can decline this ticket.

(If you need to fix these APIs to not be stable, please make sure to backport any applicable patches to 1.42 branch).
