Yes, although I think even for newly created models it doesn't always make
sense to differentiate roles of an entity via sub-classing/delegation, e.g.
when the roles are dynamically retrieved from a database or similar.
Even from the database, you can map it as subclasses or delegation. I've
spent enough time in the ORM space to know that's actually a natural way
to do it ;)
