This is useful e.g. for GDExtension physics servers: they need to register a
PhysicsDirectBodyState3DExtension(orPhysicsDirectBodyState2DExtension) class, which typically uses direct access to a body via a pointer, but if the class is registered normally then the editor crashes on startup because it instances the class (without setting the body pointer) and tries to find default values for properties.Depends on godotengine/godot-cpp#883 for CI to pass.
