[wildfly-dev] regression caused by "WFLY-3175 Create non-clustered implementations of org.wildfly.clustering.api services" change

I'm running with an older WildFly configuration (EE TCK) that probably doesn't have the needed changes for the "jboss.clustering.registry.ejb.default" service. Rather than just syncing up with the WFLY-3175 changes, I would like to know if the dependencies on "jboss.clustering.registry.ejb.default" should be optional so that people with older WildFly configurations do not get service dependency errors on "jboss.clustering.registry.ejb.default"?
