The honest answer? I have no idea! But I can share what I do know and/or heard when I worked there. I have zero knowledge about NX-OS. But I can say that the XR and XE teams were quite isolated from one another. For instance, as an XR dev, I had no visibility into XE development. It kind of makes sense: XE and XR target different device segments, which means the feature sets and scale and availability requirements were different. But both were spun off from IOS, which is why the “base” is common. I don’t have any visibility into what they’re doing now, but I wouldn’t be surprised if they’re working to unify XE and XR at some level.
