The important metrics I'd be interested in is the Bus Factor, the Active Maintenance and Passive Maintenance activity as well as when the last release tag was created. Bus Factor could be a bucketed 90-percentile count on the contributors. Active Maintenance and Passive Maintenance could be established by looking at PRs and Issues and how many commits aren't directly related to them. Last Release Tag is easy.
