Running `borgcfg up` is very different than spending weeks writing monarch configs :P
I totally agree that Google's tooling is _legendary_ when you understand it all, but I also agree that having to learn 15-20 different config languages to get a service running in production was pretty damn painful when we only had three months to do it. There's also been a good amount of work in the world outside of google to get tooling to a similar place (and in many cases, without 20 years of baggage).
