Is it necessary to put all the logic inside a “wrapper” class in order to make the Document Class clearer?

class MyDoc extends Sprite{  
private var theLogicHolder:MainLogic  
function MyDoc()  
{  
theLogicHolder = new ManLogic();  
}  
}

Or is this just a nonsense superfluous stuff (to make the swf bigger and slower)?
