iOS Sticker Pack Extension with AIR?

Apple recently released iMessage "Sticker Packs" with iOS 10, which can either be delivered as standalone apps for the iMessage store, or can be bundled as an Extension within an iOS app.  Bundling the stickers within your app is in interesting feature, since your app users will automatically get the stickers when they download or purchase your app.  From what I understand, making the sticker pack is fairly straightforward with Xcode, but I'm not sure how to bundle it with an app created with AIR.

Is there any current way that AIR supports bundling iOS App Extensions when creating an ipa?  Or are there any plans for this?

It sounds like the sticker pack would be packaged in the main app's ipa, but outside of the Payload directory and in its own folder structure.

Documentation is a bit scarce, but here are some related links from Apple's site:
