 - **`SkipFirebaseFunctions`** lacks `async`/`await` call signatures, streaming RPCs, and per-call options. Only completion-based callback calls are supported.
 - **`SkipFirebaseRemoteConfig`** does not yet expose `addOnConfigUpdateListener` (real-time config updates) or custom signals.
 - **`SkipFirebaseAppCheck`** ships only the `Debug` provider factory; custom provider implementations are not yet bridgeable.
-- **`SkipFirebaseInstallations`** is essentially a no-op beyond fetching the installation ID.
+- **`SkipFirebaseInstallations`** cannot bridge the `InstallationIDDidChange` notification or the `InstallationIDDidChangeAppNameKey` userInfo key. The Firebase Android SDK has no equivalent push-notification mechanism for installation ID changes — it exposes no broadcast, callback, or listener that fires when the ID rotates. As a result, any code that observes `NotificationCenter.default.publisher(for: .InstallationIDDidChange)` on iOS will compile on Android but never receive an event. If your app relies on this to, for example, re-upload the installation ID to your backend after it changes, you will need an alternative strategy on Android (such as fetching the ID on every app foreground, or polling after Firebase SDK upgrades).
