Feedback Request - OnDestroy(applicationQuit)

Hello!

One feature I end up using over and over again is detecting whether the OnDestroy function is running when application is quitting:

Code (CSharp):

1. bool applicationQuitting;
2.  
3. private void OnApplicationQuit()
4. {
5.         applicationQuitting = true;
6. }
7.  
8. private void OnDestroy()
9. {
10.         if(applicationQuitting)
11.                 //do stuff
12.         else
13.                 //do other stuff
14. }

Now, this is fine, and not a big deal of course. But it would be *amazing* if this could be built in, assuming it could be optional since otherwise it would break old code XD
