I'm used to using a Continuous Integration (CI) system which doesn't allow code to be merged unless it builds and tests pass. This does not allow for super fast merging as builds take time and testing takes time. But it prevents builds from breaking. The system I have been using is: https://zuul-ci.org/ https://zuul-ci.org/ Not exactly what the main focus of the article. But when the article talks about "the build is broken" then using a CI system which prevents that is good. It doesn't prevent an individual developer from breaking their local build of course.
