Component used: Navigation Compose

Navigation Compose's NavHost (and any other Compose related Navigator), must all use the same pattern of:

val saveableStateHolder = rememberSaveableStateHolder()
CompositionLocalProvider(
    LocalViewModelStoreOwner provides backStackEntry,
    LocalLifecycleOwner provides backStackEntry,
    LocalSavedStateRegistryOwner provides backStackEntry
) {
    saveableStateHolder.SaveableStateProvider {
        destination.content(backStackEntry)
    }
}

It would be nice if we could extract that out into a reusable container, so that any Navigator could write:

val saveableStateHolder = rememberSaveableStateHolder()
backStackEntry.compositionLocalProvider {
    destination.content(backStackEntry)
}

Where a fun NavBackStackEntry.compositionLocalProvider(content: @Composable () -> Unit) would encapsulate all of the details for you.

I'm not particularly tied to the name / use of an extension, but I like the reuse of CompositionLocalProvider in a way that doesn't add an overload in a different package to the global namespace.
