Forms with only one configuration object, as defined by getEditableConfigNames(), still use a detail #type element for the configuration object wrapper. (At least, they do in the default implementation of getContainerTypeForDepth().)
This is an unnecessary HTML element for a form that is not going to have other container elements at that level.
If there is only one editable config object defined in getEditableConfigNames, both depth 0 (wrapper for all config object wrappers) and depth 1 (wrapper for all elements on a single config object) should be 0 in the default implementation of getContainerTypeForDepth().
