I'd say the microservices fad is newer than the distributed source repositories but disregarding something because deemed 'new' doesn't make a good argument. And in the Java world at least modules aren't real. The statement shows lack of understanding how modules should be utilized (it has very little to do with packages). Interfaces (can) do exactly the same what protocols in microservices do. Enforcing that might be harder but facades/proxies ensure there would be no (feasible) way to bypass. There is no substitute for good data models/responsibility.
