I went to Microsoft Ignite 2018 for the first time this year. During the week, I got to chat with lots of folks, including some of the SCCM/ConfigMgr product group. Mark Silvey was kind enough to chat with me about plans for the OData connector that was first introduced in ConfigMgr 1612 Technical Preview. When it was first released it was called CMRestProvider and it had to be enabled in the console (you can read more about this initial implementation here).
