Are these RealityKit warnings a cause for concern?

I've created a minimal iOS RealityKit/ARKit app with only this view controller:

import UIKit
import RealityKit
import ARKit

class ViewController: UIViewController {

    var arView: ARView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        arView = ARView(frame: view.bounds, cameraMode: .nonAR, automaticallyConfigureSession: true)
        arView.autoresizingMask = [.flexibleWidth, .flexibleHeight]

        view.addSubview(arView)
    }
    
}

When I run this app in the iOS 18.1 simulator using Xcode 16.1 beta 2 (16B5014f), RealityKit logs the warnings included below to the console.

I see similar warnings on the device, running iOS 18.0.

Should I be concerned about any of these warnings?

Please let me know if I should submit feedback reporting this issue.

Thank you.
