No, there is more complexity: you have the class hierarchy and 
_additionally_ you define at throwing site how the exception needs to be 
handled.  With the current language design that distinction is bound to 
the exception type while the suggested approach allows to vary handling 
per exception type; hence there are more degrees of freedom and 
consequently more complexity.

Kind regards
