Yes, of course. Nearly all serious Squid deployments should
automatically archive and process some of the cache manager reports.

Yes, there were several lengthy (but reasonably fruitful) discussions on
squid-dev and even a couple of failed initial implementation attempts
predating (and triggering) those necessary discussions.

I believe the long-term goal is a YAML-compliant output with a
stable/published basic structure that would be easy to consume using
modern tools. Properly migrating to that kind of output requires a lot
of basic low-level development work based on serious internal API
changes that I have been unable to find enough free time to implement.
