Bingo. Couldn't agree more. The other posters in this comment chain seem to view things from a dogmatic approach vs a pragmatic approach. It's important to do both, but individuals should call out when they are discussing something that is practiced vs preached.

Agreed. What I’m describing here isn’t solely pragmatic it’s axiomatic as well. If you model this as a distributed system with graph all microservices by definition will always reach a state where the apis are broken.

Most microservice companies either live with the fact or they have round about ways to deal with it including simultaneous deploys across multiple services and simultaneous merging, CI and type checking across different repos.
