No way to access categories config node

[cdhunt]

In the plugin.json example there is a categories node outside of the agents list, but it looks like when the config is loaded from file, everything but agents is discarded. I'd like to use this section as a global config space instead of relying on an app.config. Is there a way to access that w/o writing my own config reader method or was it intended to be accessed by custom methods only?

"categories": {
    "big": [1, 2, 3],
    "enabled": false
  }
