@markap14 I agree that this behavior should not hold up the initial
integration. It is an edge case and users are unlikely to observe it.
However, I can see users wanting to reference a versioned flow multiple times
from various spots in their flows and creating multiple instances of that
versioned flow within other process groups, and as you mentioned it could be
confusing for the user. We should probably note the expecting syncing behavior
with the NiFi Registry in the documentation. I can create a separate JIRA for
addressing this particular case.
