With the proposed change -- failing at "step 3", it doesn't. It fails at the 
time that you try to create the instance, saying the class was not found, 
which is actually the case.

No, the dev didn't mean \Exception, he meant *his* exception, the one that he 
has in the current namespace, and any way your setting would not have 
resulted in any error, because for the dev, autoload worked.
