Hey, Flynn cofounder here. We merged the repos (there were a few dozen!) after encountering a ton of friction landing project-wide changes and managing the build system (vendoring dependencies in every repo got ridiculous).

Contributors were also having a lot of trouble figuring out where to report issues and submit patches. On the whole the unified repo and build system has been a massive improvement to our productivity and the quality of the project. Unfortunately using components in a modular fashion can be harder, and we haven't come up with a great solution to that. We're still committed to keeping our components independently useful and would love to get feedback on what we can do better.
