That's not what "microservices" is.
If you are not familiar with the concept then you should refrain from post personal assertions on guidelines or best practices.
That's how it sometimes ends up. You said:
> For starters, the main selling point of microscopes is not performance. It is organizational advantages. It is a way to draw clear and crisp lines regarding ownership and ops.
But that's just regular old services. The "micro" in "microservices" usually implies smaller services, and one extreme of that is having more services than engineers. That's something I saw happen, heard about and read about. Microservices can be abused by making them too small and making too many of them. Uber is an example of that.
