I don't follow you there - in my mind, the default getattribute could simply have wrapped all its operations inside soem kind of "try..catch AttributeError:" mechanism, and thus been able to fallback to getattr in any way.

But then it would be incorrect to say that "getattribute raises an exception".

When we say that a function raises an exception, we normally mean that the exception propagates out of the function and can be seen by the caller, not that it was raised and caught somewhere inside the function.
