+ * - ensures both the old and new components are interchangeable by enforcing that they accept the same props.
+ * - ensures that both old and new components are lazily loaded via React.lazy.
+ *
+ * Example usage:
+ * const WatchlistTab = withK2Alpine(
+ *  lazy(() => import('screens/watchlist/WatchlistTabView')),
+ *  lazy(() => import('screens/watchlist/WatchlistTabViewK2Alpine'))
