Wow, that really got me thinking. ..  I suspect this line of thought
is related to the quote
you sent from Martin, in which he talks about not designing the
solution by mimicking the
domain entities and their relationships, but rather by.. I guess..
finding the "essence" of the
responsibilities that have to be provided for in the domain (aka the
behaviors) and then modeling
those.
