I'm not sure that your remark regarding a data service layer is any different than the coding practices associated...
with any shared or common reusable service. My take on this is to reduce the number or quantity of abstraction levels within your code. My perspective of developing a data services environment is to ensure that all code that communicates to the defined interface is self-contained (prior to passing the data to the interface). In the days of writing shared components (shared code libraries, objects, etc.), problems would inevitably crop up when someone changed the underlying code without telling anyone else. The focus should be to only interface to shared or common services that don't change.
