Can you explain this a bit more? I thought the point was to have each service be as atomic as possible, so that a change to one service does not significantly impact other services in terms of rollbacks/etc.

If I'm wrong here let me know, our company is still early days of figuring out how to get out of the problems presented by monolith (or in our case, mega-monolith).
