This is expected behavior...

Saving or pulling the flow is happening on behalf of the end user in
nifi which is being proxied by the nifi server over to registry. In
this case, the nifi server only needs proxy permissions.

Checking the status of all the versioned PGs happens in the background
as the nifi server itself, so it needs read access to all buckets.
