Churn Reports

The purpose of the Churn report is to flag certain changes in values where based on past experiences, the changes can be disruptive from platform experiences on Windows, Android, iOS, Chromium, etc..., (based on customer and developer feedback).
The scope of the Churn report is limited to a subset of data. It's available from CLDR v38 release and can be found in github CLDR-Staging; for example, see v38 Churn.tsv.
