How do you individually deploy and operate modules, packages, and libraries? The purported benefits of micro services have always been harmonizing with Conway's law. In particular, one of the nice benefits of microservices is that it's harder to "cheat" on the architecture because it likely involves changing things in multiple repos and getting signoff from another team (because again, the code organization resembles the org chart). The high-level architecture is more rigid with all of the pros and cons entailed.

I suppose if you work in an organization where everyone (including management) is very disciplined and respects the high level architecture then this isn't much of a benefit, but I've never had the pleasure of working in such an organization.

That said, I hear all the time about people making a mess with micro services, so I'm sure there's another side, and I haven't managed to figure out yet why these other experiences don't match my own. I've mostly seen micro service architecture as an improvement to my experiences with monoliths (in particular, it seems like it's really hard to do many small, frequent releases with monoliths because the releases inevitably involving collaborating across every team). Maybe I've just never been part of an organization that has done monoliths well.
