Well, we kind of started evaluating it (there was definitely not enough
time around pike/queens as we were busy landing the bundles code), then
due to discussions around k8s it kind of got off our radar. We can
at least resume the discussions around it and see how much effort it
would be. I'll bring it up with my team and get back to you.
