Having access to the hash allows to produce stats in other ways (such as StatsD) without having to parse JSON of data that is available in memory. An example of this workaround is fa6ba1f507/lib/puma/plugin/statsd.rb (L112-L114)
[changelog skip]
We needed `backlog` and `running` when we introduced the stats endpoint
in [c5aad50e][]. We changed the endpoint to use `@cli.stats` instead in
[c48b804d][], so these values are no longer needed.
