Why does the sample use Task.detached?

I was wondering if anyone knows why the sample project uses Task.detached everywhere because it seems highly non-standard, e.g. in ContentView:

.task {
    Task.detached { @MainActor in
        await flightData.load()
    }
}

Instead, I would expect to see something like:

 .task {
    flightData = await controller.loadFlightData()
}

Or:

.task {
     await controller.load(flightData: flightData)
}

Is the use of detached perhaps an attempt to work around some issue with ObservableObject published updates?
