It was made the way it is by considering at least three things, one, most times there will be a type cast to the new TForm class is being used to create an instance and the component or property editor is well aware of the right class to be used, two, FindEditorForm allows access to other component or property editors forms, and the more isolated are they the better. 

At the same time it opens the door to other kinds of 'form' editors which are not descendants of forms. Btw, what if somebody uses TCustomForm as parent class instead of TForm?, So the way was planned accounted also flexibility.
