 The v2 API prioritizes the following principles:
 
-**Readability and Maintainability**: Extensive use of `async`/`await` improves code clarity and simplifies maintenance.

-**Developer Control**: Developers own the `main()` function and have the flexibility to inject dependencies into the `LambdaRuntime`. This allows you to manage service lifecycles efficiently using [Swift Service Lifecycle](https://github.com/swift-server/swift-service-lifecycle) for structured concurrency.
