Certainly in general that's true - we have the training and experience
creating software they don't.

They probably don't even suggest an "implementation".  But what I'm saying
is developers are looney tunes if in general they don't implement the app
*as a closely as possible* to the domain model.  In other words, they
should attempt to preserve as much traceability as possible between
physical implementation and the domain object model.  

The benefit of doing so is increased intuitiveness and understanding for
other initial developers and for enhancement/maintenance developers. 
Those are the major wins and goals of OO modelling - greater intuitiveness
and understandability, both of the domain and the implementation.
