I disagree.

We use several persistence frameworks that require this, and have 
just not found it a big deal.  We also have done experiments with 
toolsets like hibernate that do not require such extension, and have 
not found it terribly freeing.  Sure, there is some benefit, but not 
nearly the amount you are making it out to be.

Our own framework (in Java) uses interfaces that must be implemented, 
but this has many of the same problems.  Personally, I find 
augmentation with composition cleaner in theory, but this has not 
translated to a lot of benefit in actual use.
