A suggestion for the basic _config_get

Is there any reason not to include 
```
        'result': serialize_settings(node_addon, user)
```
in the default return value? 
The more I work on the clinical trials addon, the more I question how general this cookiecutter code should be. I've ended up ripping the bulk of this code as it isn't relevant to my addon. That said this addon is a little unusual (no auth, no UserSettings model).

Are we shooting for the maximal intersection of code common to all addons, or are we expecting developers to have to cut out code as well as add code?
