I don't really understand the problem with multi-repos. Maybe because I'm a FE developer, I'm shielded from some of the pain of launching an external service locally, but I find the process of needing to update an external module to be rather similar to open source dev: clone, link, fix, PR, approve, merge, update package.json. It's that simple. The only part that can present itself as somewhat tricky is how your environment handles linked dependencies, but that can be resolved if you've configured your webpack or whatever correctly.
