> Most mature languages have a logging system which allows the internal logging of a library or module to be silenced, redirected or almost any other action. I think there is a lot of value in libraries doing appropriate logging which can't easily be replicated in application code.

Info/debug level logs sure, I don't disagree. As long as there is some built in or community standard logger and not the libraries own custom thing.

Errors, I'd rather they throw and my own app's logging facilities kick in that can provide more context: which server, which container, request info (method, path, request ID), etc. Granted some of that could come from configuring a logger with it.
