One the other hand, I've seen and read about companies where some forms of reused code are actually seen as code smells in this context. Especially when it comes to models, as one's service idea of what constitutes a 'Customer' might be different from others. Managing that (and redundant data stored in each microservice's private area) requires some heavy tooling...

So I'm always interested in the more specific approaches to communication and storing data when it comes to microservice architecture, which might be an idea for a sequel article ;)
