[hibernate-dev] [OGM] Neo4j integration dependencies

Is there any particular reason why we would not want to create three
artifacts, besides backward compatibility? It seems the obvious and ideal
solution, but I might be missing something.
If there is common code, we can always create a fourth -neo4j-core artifact
that would have no interest to users but would simply ensure we don't
duplicate code, and would be delivered through transitive dependencies.
About backward compatibility, I guess there are two options:
- If the last released version of the artifact used to contain only the
embedded mode, we can use maven relocation
- Otherwise, we can advertise this artifact as deprecated, remove almost
everything in it and add the relevant new artifacts as dependencies.
Or am I being too naive?
