I am aware of environments where access to a Git server from the operational host/cluster that's running NiFi and NiFi Registry would not be available due to security or other constraints. Loss of a non-Git based Flow version control option would impact such environments. That said, I imagine such setups are in the minority, which is possibly why there's been less momentum in that regard over the past couple of years.
I can see the utility in separating the Registry component to its own repository again would alleviate concerns around the main Apache NiFi repo containing infrequently maintained code where vulnerabilities are increasingly likely to be identified, etc. It would, however, as Shane says, make it harder to maintain the UI inline with NiFi, although when the community might get around to uplifting the existing Registry UI is another question.
