Badges with numeric or other data

In taking a look at https://help.github.com/en/actions/automating-your-workflow-with-github-actions/configuring-a-workflow#adding-a-workflow-status-badge-to-your-repository (whose example URLs give 404s), I see that:

> Status badges show whether a workflow is currently failing or passing.

Are there plans (or third-party workarounds) to allow numbers or other text to be displayed as the result of Github Actions (i.e., not just a Pass/Fail status)?

I’d love to show coverage without needing another third party service.
