EditorSceneManager.sceneSaved callback marks scene dirty. Can this be suppressed?

In Unity 2018.4.11f1:

I have GameObjects in my scenes that I use as markers for easy visual placement in my scenes. However, I do NOT want the visual components saved into the scenes. Therefore In my code, I have the following

Code (CSharp):

1.  
2.             private void Start(){
3.                
4.                 EditorSceneManager.sceneSaving += OnSceneSaving;
5.                 EditorSceneManager.sceneSaved += OnSceneSaved;
6.            
7.             }
8.  
9. // later ...
10.  
11.              private void OnSceneSaving(Scene scene){
12.  
13.                  // Remove things from scene before saving
14.  
15.              }
16.  
17.              private void OnSceneSaved(Scene scene){
18.  
19.                  // Re-add the removed things to scene
20.                  // ... But now the scene is dirty again!
21.  
22.              }
23.  

Inside OnSceneSaving, I remove visual items from the hierarchy that should not be saved into the scene.

Inside the OnSceneSaved callback, I restore the things I don't need to save into the scene, but in doing so I have marked the scene dirty. But I don't want the scene to be marked dirty! It doesn't have changes that I care about.

Is there a way to suppress this, so that I can re-add the visual markers into the scene without marking the scene dirty?

 

Resolved : The issue actually was with a different component in the scene. As it turns out, the approach above works just fine.
