Announcing updated policy reporting experience in Microsoft Endpoint Manager

I wanted to get some informations about the REST API for https://graph.microsoft.com/beta/deviceManagement/reports/getConfigurationPoliciesReportForDevice (this one was mentioned in your article).  Unfortunately at this time, this API call is not documented at all on https://docs.microsoft.com/en-us/graph/api/overview?view=graph-rest-beta ("Microsoft Graph endpoint reference")

My understanding is that these API calls are considered as "production ready" on your side. However, even if you say the old API calls will stay intact, the new calls are not even described in the /beta endpoint "Microsoft Graph endpoint reference". Why so?  How can your customers follow your advise to move "any automation over to using updated endpoints"...when there is nothing published publicly as of today?
