Remove this script as it does not reliably detect unused resource properties in a generic manner.

Is there any consistency issue by switching to ARG? Per my understanding, there may be latencies there and hence some data may not be quired back immediately after new operations and hence may introduce confusion/troubles for scenarios like troubleshooting.

Hey @feiskyer, what I know the consistency issue has been resolved and is no longer a concern. Latency remains a known issue, but it's not specific to ARG, so I don't believe it's a blocker.
