Hello My preference is that we follow similar logic to how NiFi has 'instance configuration' details in nifi.properties and 'flow configuration' details in flow.xml.gz.
What we do in minificpp will hopefully be aligned with what we do in minifi-java and hopefully minifi-java just becomes an assembly of nifi.
