The use case is building custom feature-packs (as documented there: https://access.redhat.com/documentation/en-us/red_hat_jboss_enterprise_application_platform/8-beta/html/using_jboss_eap_on_openshift_container_platform/assembly_capability-trimming-in-jboss-eap-for-openshift_default#provisioning-user-developed-layers-eap-foropenshift_assembly_capability-trimming-in-jboss-eap-for-openshift).

We need this dependency when building the custom feature-pack.

The workaround would be to use the upstream maven plugin:org.wildfly.galleon-plugins:galleon-maven-plugin:6.2.0.Final
