Would it make sense, could we gather, the total of archived_repositories?
We just had a situation that was only discovered because of odd messages in the backup logs. A team had automation that went unchecked and was creating and deleting repos at a rapid pace. The number of deleted repos in their org exceeded 17,300.
If Hubble were to report this, and we see a spike in the number of deleted / archived_repositories we could investigate further. For the most part I would expect the total to be very low.
This was an odd case that we only caught due to the backup logs and further investigation.
