To have Bundler report anonymous usage metrics over HTTP to rubygems.org when a heavy command is run (to avoid deteriorating the runtime), and to have a backend API endpoint in rubygems.org to instrument it.
Basically, yes. The actual implementation changed a little bit, and we decided to only instrument the low cardinality metrics using Datadog, as the free Datadog version limits value cardinality and wouldn't work with, for example, time related metrics. Changing it into another metric instrumentation database has been left out of this project for another time.
