alt Hacker NewsI was coming here to say this. That the whole idea of a shared library couples all those services together. Sounds like someone wanted to be clever and then included their cleverness all over the platform. Dooming all services together.
Decoupling is the first part of microservices. Pass messages. Use json. I shouldn’t need your code to function. Just your API. Then you can be clever and scale out and deploy on saturdays if you want to and it doesn’t disturb the rest of us.

Yes, but there’s likely a lot of common code related to parsing those messages, interpreting them, calling out to other services etc. shared amongst all of them. That’s to be expected. The question is how that common code is structured if everything has to get updated at once if the common code changes.
