I read through this yesterday and didn't have any specific comments to leave in-line, but I am happy to see this surface now as I know it's come up in a number of settings in the past.  I also thought it was interesting to see the open, implicit acknowledgement of seeking inspiration of convergence with the analogous feature set in Kubernetes. This feels like a healthy thing to see continuing to happen in this community, but I'm also curious to know whether there's any more to it that is worth sharing in this particular case.
