We used CloudEvents internally at Segment as an evolution of the existing ad hoc format that evolved naturally over time. We were generally happy with its ability to bring some semblance of order, documentation, and guidance to our event format while also being flexible to changes. For example, we layered on the ability for internal services to return 207 Multi-Status responses to batched events and it didn't require major hacks.
