Should ServiceExt::serve() return after initialization?

[the-isz]

Looking at examples/servers/src/counter_stdio.rs (but other examples and README.md use the same code):

let service = Counter::new().serve(stdio()).await.inspect_err(|e| {
    tracing::error!("serving error: {:?}", e);
})?;

service.waiting().await?;

The above code implies to me that ServiceExt::serve() returns either a RunningService or an initialization error after being awaited.
After the successful initialization I expect that I can do other stuff and then eventually wait for the service to shut down (e.g. via the second line).

However, any code I add after the first line is never reached.
So I think something is wrong here.

Either I'm misunderstanding the API and ServiceExt::serve() is not supposed to return after initialization.
But then I wonder why we even have the second line in the example and how I'm supposed to do other (asynchronous) stuff after starting the service.

Or this is a bug and ServiceExt::serve() is supposed to return after initialization.

Thank you for your help!
I'm really impressed by this package and glad it sees so much development!
