UpdateAttribute Failure Relationship

[Dan S]

My team is requesting a failure relationship for UpdateAttribute as seen in
NIFI-5448 <https://issues.apache.org/jira/browse/NIFI-5448> and NIFI-6344
<https://issues.apache.org/jira/browse/NIFI-6344> as we are
experiencing the same problem where a NIFI Expression Language is throwing
an exception. In the PR for NIFI-5448 it was mentioned this feature would
have to wait until NIFI 2.0.0. I wanted to know if there is any active work
regarding this and whether eventually there will be a failure relationship
added to UpdateAttribute?
