Right. That happens only with "direct WMS integration". I.e. hitting gwc through the /geoserver/wms or /geoserver/ows?service=WMS end points. Reason is the feature was added to support GeoNode's dynamic changes of styles and feature edition. That said, it would be a good thing to be able of configuring that. It's just that there are so, so many things that can or could be configured, that's hard to draw a line. But in any case, feel free to raise a jira issue about it.
