jboss-eap-8.1.0.Beta-CR6.1-maven-repository.zip doesn't contains any wildfly-galleon-plugins artifact

Manifest contains this info about wildfly-galleon-plugins:

$ cat org/jboss/eap/channels/eap-8.1/1.0.0.Beta-redhat-00012/eap-8.1-1.0.0.Beta-redhat-00012-manifest.yaml | grep -A 1 -B 1 wildfly-galleon-plugins
  - groupId: "org.wildfly.galleon-plugins"
    artifactId: "wildfly-galleon-plugins"
    version: "7.3.1.Final"

mrrc-only-maven-repository.zip contains wildfly-galleon-plugins-6.4.8.Final-redhat-00001.jar

My understanding is that channel should contains productized version of wildfly-galleon-plugins and such version should be in maven-repository.zip
