When an application is using for example the OidcConfigurationServletListener and have a dependency defined in the jboss-deployment-structure.xml on the org.wildlfy.security.elytron-http-oidc module, the server logs a WARN message about the usage of a private module, see:

16:37:56,022 WARN  [org.jboss.as.dependency.private] (MSC service thread 1-5) WFLYSRV0018: Deployment "deployment.simple-webapp-oidc.war" is using a private module ("org.wildfly.security.elytron-http-oidc") which may be changed or removed in future versions without notice.

To prevent users from this logging, the module should be made public.
