As part of the current Jakarta EE 11 TCK refactoring work we will need new launchers to replace the CTS command line runners for application client and embedded EJB tests. When I tried adding an application client Arquillian container to the https://github.com/wildfly/wildfly-arquillian repo, I found I could not use classes like 
org.wildfly.core.launcher.AbstractCommandBuilder due to package private access on the class.
 
Is there is a requirement that all launchers exist in the wildfly-launcher module?
