The change by itself looks good and I fully understand the intent/benefit. My only comment is that it could potentially surface user data in the UI through bulletins and this might be problematic in some secured environments. Also this means we don't have full control of what is rendered in the UI (cc @alopresto for visibility).

[MikeThomsen]

I agree with @pvillard31. While it's fine most of the time, there are NiFi users such as government agencies and healthcare providers where most of the NiFi users should not have minimal ability to inspect the data for legal and policy reasons.

We're marking this PR as stale due to lack of updates in the past few months. If after another couple of weeks the stale label has not been removed this PR will be closed. This stale marker and eventual auto close does not indicate a judgement of the PR just lack of reviewer bandwidth and helps us keep the PR queue more manageable. If you would like this PR re-opened you can do so and a committer can remove the stale tag. Or you can open a new PR. Try to help review other PRs to increase PR review bandwidth which in turn helps yours.
