No. A lot of orgs don't require setting up Bazel to make simple things like generating code from protobufs work
Including the build commit is very straightforward - but more to the point, Google projects frequently treat the monorepo like a service to do things like fetch the latest config. Even deployments tend to be automated through the monorepo - lots of tools make automated change requests.
You revert the offending commit. That triggers an automatic deploy (or, even more likely, your buggy change gets caught in the canary stage and automatically reverted for you).
The Google philosophy is called "live at head" and it has a bunch of advantages, provided your engineers are disciplined enough to follow through.
Protobuf is built specifically for Google and Google's way of doing things. Not everyone is built like Google.
Yes, Google's internal infrastructure is that good. It's easy to get caught up in the "haha cancel products" meme and forget that this company does some serious engineering.
