Provided your megawidget exposes only one single top level widget 
(usually a frame which holds all the internal widgets) to the user of 
the megawidget it will make no difference.  The user of the megawidget 
can do anything they like to the outer container as far as 
pack/grid/placing it, zero impact on your bits and pieces inside that 
container.
