You might wonder why not just put everything that is “infrastructure related” in a dedicated directory inside the Business-Module. That’s the approach often taken in many designs in the wild, but the problem with such a weak separation is that it tends to erode (and after many months you discover that a business class peeks messages in a broker). Another problem is that it’s much harder to find the boundary for unit tests (whereas with BM and IM separated, you can just assume that the public API of BM is what should be unit tested).

The quality of the design will be increased if the module is designed as if it meant to be extracted into a separate microservice in the future. It doesn’t matter when or if ever it’s going to be pulled away. It’s also not about preparing technical infrastructure for the extraction itself (e.g. http or event queues between modules) - that would be overkill if applied to all modules. This heuristic is more about the quality of choices of boundaries and responsibilities.
(There are other emergencies that could bring us to this point. One is a fire, which could result from machinery shorting. Another is a toxic ammonia leak. But these are even more unlikely.)
