What benefit of OpenTelemetry.Instrumentation.Runtime in .NET 9?

https://github.com/open-telemetry/opentelemetry-dotnet-contrib/tree/main/src/OpenTelemetry.Instrumentation.Runtime#metrics

I read:
".NET 9 introduced built-in runtime metrics. As such, when applications target .NET 9 or greater this package registers a Meter to receive the built-in System.Runtime metrics. See the .NET Runtime metrics documentation for details of the metric and attribute names for the built-in metrics."

But I still don't understand, what's the benefit of this package?

You can have a look at the following lines:

https://github.com/open-telemetry/opentelemetry-dotnet-contrib/blob/main/src/OpenTelemetry.Instrumentation.Runtime/MeterProviderBuilderExtensions.cs#L38-L41

If you are Running .NET 9 or greater it only calls the AddMeter method to activate the export of the metrics you linked. In that case the package saves you only one line.
