I haven't had a chance to try it at scale yet, but I've been looking at josh (Just One Single History): https://github.com/josh-project/josh

which goes at more-or-less the same problem from the other direction. Josh helps with treating a monorepo as separate repos, as opposed to git x-modules' approach of treating separate repos as one repo. Either way, the idea is to try and get the benefits of both monorepo and multi-repo styles, while avoiding/mitigating the disadvantages.

HN talked about it 11 months ago: https://news.ycombinator.com/item?id=27844363

Anyone have experience/updates to share since then, or a comparison with git x-modules?
