We discussed with Paul earlier today to go the way of making this explicit per channel, since currently there is a info when booting the default ha profiles:

18:06:44,039 INFO [org.jboss.as.controller.management-deprecated] (ServerService Thread Pool – 21) WFLYCTL0028: Attribute 'default-stack' in the resource at address '/subsystem=jgroups' is deprecated, and may be removed in future version. See the attribute description in the output of the read-resource-description operation to learn more about the deprecation.
