There is missing warning if following configuration is migrated to messaging-activemq subsystem:

<remoting-interceptors>
                <class-name>
                    org.jboss.qa.hornetq.apps.interceptors.LargeMessagePacketInterceptorImpl
                </class-name>
                <class-name>
                    org.jboss.qa.hornetq.apps.interceptors.LargeMessagePacketInterceptorImpl
                </class-name>
</remoting-interceptors>

There should be warning like:
WFLYMSG0082: Classes providing the remoting-incoming-interceptors are discarded during the migration. To use them in the new messaging-activemq subsystem, you will have to extend the Artemis-based Interceptor.

as for migration of remoting-incoming-interceptors and remoting-outgoing-interceptors.
