Is there a reason this signaling approach is undocumented? (godot 4 c# signals)

[MS-Painter]

So I'm new to Godot and I was trying to wrap my head around clean approaches to signaling, especially between scenes.

I ended up with something that works well, but seems like Godot isn't yet really addressing or smoothly integrating? -

I create a new Resource like so:

using Godot;

public partial class MoveToScreenSignalResource : Resource {
    public delegate void MoveToScreenEventHandler(ScreenMoveDirection direction);
    public MoveToScreenEventHandler MoveToScreen;
}

Take note that I'm not using the [Signal] attribute, this is because I want to expose MoveToScreen which the attribute doesn't seem to allow.

Now all a Node has to do is get a reference to this resource:

[Export]
public MoveToScreenSignalResource MoveToScreenSignalResource { get; set; }

I invoke it like a regular c# event:

MoveToScreenSignalResource.MoveToScreen.Invoke(ScreenMoveDirection.Ahead);

And subscribe to it like a regular c# event:

MoveToScreenSignalResource.MoveToScreen += OnMoveToScreen;

Why is this valid approach not documented or used anywhere? Am I Missing something?

And yes. I'm aware this is just using C# Events, but Godot Signals generate pretty much the same objects while having less support.
This approach is much cleaner and less problematic than any documented way I've found for Signaling between scenes, such as the autoload approach.
