Just speaking to multiple git repositories: could you use submodules for a conglomerated-monorepo?

Otherwise: you can pull in repos as bazel-file-containing additions. I forget the details, but I believe it's something like https://bazel.build/extending/repo . The troubleshooting-while-developing experience is not great though imo, I'd try submodules first.

Thanks - repository_rule looks good. So it's either git submodules to maintain updates or checksums / commits in repository_rule - I probably need to just play around with both approaches and choose the one that annoys me the least :)
