Player Loop

I played with player loop lately. I made this sample for others:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Experimental.LowLevel;
5.  
6. [ExecuteInEditMode]
7. public class PlayerLoopChange : MonoBehaviour
8. {
9.     PlayerLoopSystem pls;
10.     private void OnEnable()
11.     {
12.         pls = PlayerLoop.GetDefaultPlayerLoop();
13.  
14.         Debug.Log(pls.type);
15.         for (int i = 0; i < pls.subSystemList.Length; i++)
16.         {
17.             Debug.Log(pls.subSystemList[i].type);
18.             if (pls.subSystemList[i].type == typeof(UnityEngine.Experimental.PlayerLoop.EarlyUpdate))
19.                 pls.subSystemList[i].updateDelegate = EarlyUpdate;
20.        
21.         }
22.  
23.         PlayerLoop.SetPlayerLoop(pls);
24.     }
25.  
26.     void EarlyUpdate()
27.     {
28.         Debug.Log("EarlyUpdate");
29.     }
30.     // Use this for initialization
31.     void Start()
32.     {
33.  
34.     }
35.    
36.     // Update is called once per frame
37.     void Update()
38.     {
39.         Debug.Log("Update");
40.     }
41. }

but my question is: can i do it simpler than this or can i do it with more "proper" way compare to do this?
