What’s Wrong with Microservice Dev?

I think this not so true. The author might be doing micro services the wrong way. You generally break down micro services such that they are loosely coupled and have a good defined API/contract. As long as you don't break the API you don't have to restart everything. That is not to say you never break that API. The idea of a micro service is they should be independently verifiable(test) to a good extent.
