While you are technically correct (the best kind of correct), I would challenge you to find an organization that is doing the monorepo/microservice combo correctly. And what I mean by that is with microservices, the API is the only contract. Every service should be deployable independently.

If you have a monorepo, you're almost certainly violating that somewhere, using a shared library, or a shared database, or even just blocking deployment because some other service has turned the repo red.
