Not necessarily at all, i.e. using GRPC it's all self discovered.

Definitely

That's true, having it in it's own library is certainly a possibility -> but then it's also not that far off micro/macro services anyway, except you deploy it as one piece. And basically this is my argument: If you're having it all as libraries, and you all work in a mono repo anyway, the only real difference between micro/mono is the deployment, and that with micro you _could_ independently scale up whatever the current bottleneck is, which we've used plenty of times
