Googlers deploy software on production systems on Day 2 of their on-boarding training. I've never worked anywhere that had as straightforward and usable developer tools.
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).
I guess the trick is to understand that it's all protobufs anyway, and the config langs are just ways of generating protobufs.
Outside of Google, it is useful to understand that, for example, Helm is not part of Kubernetes, in the same way that borgcfg is not part of borg and many people use borg without borgcfg.
