I think it's worth noting that the control plane and management plane are two very different things, and it'll be interesting to see how they break out. There's a bunch of sidecars in the control plane that are competing for visibility right now. Envoy has probably had the most visibility around here. Linkerd and traefik also exist. The management plane is less well defined. Istio is super-new on the open source side, and Turbine Labs is a SaaS version. I'm honestly not aware of any others here. Most of the goodies you want don't really get unlocked until you have a management plane in place, so the focus on the sidecar is kind of baffling, imho.
