When triggering the replication from the AEM Sites Touch UI via "Manage Replication" and then clicking on the 2nd wizard step on "Published References", there opens a dialog with all references which should be published along with the actual page. The CAC configs appear there as well due to https://github.com/wcm-io/wcm-io-caconfig/blob/develop/extensions/src/main/java/io/wcm/caconfig/extensions/references/impl/ConfigurationReferenceProvider.java. Unfortunately the section headline is empty.
The reason for that is that the type from the ConfigurationReferenceProvider, which is caconfig is used as a key to lookup the translation (in /libs/cq/gui/components/common/admin/managepublication/referencesdialog/clientlibs/references/js/references.js). The translations being used here are contained in /libs/cq/gui/components/common/admin/managepublication/references/references.jsp. Unfortunately that list is currently hard coded and when no entry is being found here, it falls back to the empty string (and not to the key caconfig). Maybe there is a minimally invasive way to provide a section headline in that dialog also for the caconfig references.
