The metrics in insights are currently all focused on the workflows and jobs that Circle runs.

Metrics that help me track my team's shipping speed would add a ton of value. Metrics could include:

Time to review: the time it takes for a GitHub PR to be reviewed after it is opened

Time to prod: the time it takes from when a branch is started to when the branch is merged to master and gets deployed

Number of review cycles: stats about the number of rejections a PR gets

There are lots of interesting stats here that would bring me back to the Circle dashboard even when I'm not trying to figure out why my build broke.
