I think this just makes sense in terms of grouping.

But there is also a practical aspect: I would like to start publishing directly to the Sonatype OSS repo rather than publishing through JBoss Nexus and waiting on a scheduled sync. Renaming the group facilitates removing those artifacts from the sync script.

Andrea Boriero Already has a proof-of-concept for this @ https://github.com/hibernate/hibernate-orm/pull/1259
