Having to have that documentation, finding, reading, understanding and trusting it already adds so much overhead. It is still nowhere close to ability to jumping around with IDE. It might be in a different language, different design patterns and to get to the details you have to check out that project anyway because you can't document absolutely everything out of code base. And if you do you will end up with multiple sources of truth. It is so much more likely that for every little issue which you otherwise might be able to find an answer to yourself very easily you will have to contact the team owning that microservices. It is not only mentally exhausting. It is time consuming, it requires so much back and forth. It creates so much dependence on other people because figuring out how things are related is so much more difficult. Sometimes I have 8 or more different IDE windows open to understand what is going on.
