Thanks rage_co! The post Callback after scripts finish compiling you mentioned is sufficient for what I want.

This should be a workflow for deleting a monobehaviour safely:

You want to delete the monobehaviour A.

Before deleting the script, add the method:

  [UnityEditor.Callbacks.DidReloadScripts]
     private static void OnScriptsReloaded()
     {
         System.Type monobehaviourType = System.Reflection.MethodBase.GetCurrentMethod().DeclaringType;
         Object[] objs = GameObject.FindObjectsOfTypeAll(monobehaviourType);
         foreach (Object obj in objs)
         {
             Debug.LogWarning($" Watch out! The monobehaviour {monobehaviourType} is currently being used by {obj.name}", obj);
         }
     }

Focusing on the editor again, the console will snitch all GameObjects (including prefabs) that are using such script. Double clicking each warning line will redirect to each GO.

Marking your reply as accepted. Thanks!

It's really simple to do this at runtime....for example let's say we want to give a compiler error if a certain component.... let's say CameraManager is missing...

 if(target.GetComponent<CameraManager>() == null)
 {
   Debug.LogError("Component missing!");
 }

Debug.LogError basically gives an error....hope this helps

Not in runtime?

Im not too sure in that case...maybe Editor scripting? But since i haven't had any experience with it i can't really say

I found this question and it might contain what you need "Callback after scripts finish compiling"...

Also, just a piece of advice that you should use Debug.LogWarning instead of LogError since if you give out an error each time....you will not be able to do anything in the editor and actually fix the error...so a Warning should do just fine
