I liked it. Nice article. It makes me happy about Dart&#x27;s design decisions in this area. Hopefully something nice happens for Go.<p>In the hazy future, one thing I wonder about is how to do back-pressure outside the monorepo: if upstream makes a mistake and breaks something important downstream, how quickly do they find out? Today this happens informally. Ideally (from a responsible maintainer&#x27;s point of view) you&#x27;d have an easy way of finding out before publishing a new version, and the second-best approach would be automatic notification soon after. This might involve speculatively compiling and testing some downstream packages to find out how bad the breakage is, and probably involves coordinating continuous builds somehow, or perhaps making continuous builds the job of the central repo (making it even more centralized).
