Modules are one of several packaging formats we have.  With CentOS
Stream 9/ RHEL 9, we took user and customer feedback on how the
default versions of software are packaged and determined that the
defaults should be normal RPMs.  Newer and alternative versions of
software will be delivered as modules in some cases, or as regular
RPMs with applicable versioning in others.
