The current plugin API allows plugin authors to define custom REST API
endpoints that can perform any custom validation needed for the plugin. The
repository version creation REST API provided by pulpcore only validates
that the content exists. We should document this limitation and recommend
that users use Repository Version creation APIs provided by specific
plugins.
