How is this helpful?

The current problem is that DBIC stringifies objects to their 
primary key by default.  So, if you have a primary key that is
an id (integer), it usually does not make sense to end users.
In that case you want the stringification to apply to something
else.

In my experience, a "meaningful" string usually makes a terrible
primary key, because you'll probably want to change it down the 
road.
