We've discussed the possibility of publishing the specific metadata that Quarkus uses to compile applications using Hibernate ORM into native code by using GraalVM's native-image tool.
I'm skeptical that we can provide the comprehensive metadata, especially as many details will depend on the user domain and the user configuration; all such metadata is by nature dynamic, so can't be expressed by pure metadata.
However some of the reflective rules are static; to help other people exploring such options, we can start publishing the static metadata in a new experimental jar. I see no problem in sharing this, as long as it's understood that it's not comprehensive - and since it's not we can't test it much either.
Since that's still useful, why not.
