It is always curious when someone writes that they are bowing out of a discussion, as if they don't realize that no longer replying conveys the exact same information. Was there an additional takeaway here that I missed?
Conway's law doesn't apply to microservice architecture.
Microservice architecture splits the functionality farther, than Conway's law talks about. When a single team owns 4-5 microservices - that's beyond Conway's law.
It is people who provide service. If the (micro)service produces 4-5 products as part of the service they provide, that's not beyond Conway's Law at all.
