Because it shows its needed to..  

You can not chase a problem if you dont know if the base is correct. 
If the base if incorrect you can and will inherrit other problems which makes debugging a hell. 

I dont make "assumptions" because..

And he is right on that one. 

That simple, sorry to say it like that but it is what it is.
