True, but something like a database connection string does need to be different for each build-environment you run in, ie you will surely not want the development code connecting to your production database, for example. So I would say that a DSN is a farily important thing to be able to configure,
.. unless you are going to have a configuration database, to which all code connects, and gets the dsn for it's database from there ...
but really, they do something close to this $client, there are constants that come from the database, and a constant to determine the database to go to *shudder*
