The flatten-maven-plugin looks interesting. We used it in https://github.com/hibernate/hibernate-search/pull/3588 and it effectively removes any references to BOMs/POMs from the flattened POM.

Maybe we could apply it to all public POMs? It would remove the need to publish:

• The root POM (maybe?)
• The public parent POM
• The build BOM

WDYT Marko Bekhta?
