Limitations of AppIntentsExtension member intents

When considering an intent's membership in an AppIntentsExtension vs. main target or an xcframework linked to the main target (with Xcode 16), are there certain capabilities unavailable to Extension member AppIntents? (Specifically, say reuse in AppShortcutsProvider, launching deep links via openAppWhenRun, reuse in Widgets or LiveActivities?)

For example, the Watch action button warns to only use intents in the main Watch target.

Here's an ongoing thread with a discussion of some of the limits.
