Consider deprecating old lib API

**Feature request**
It would be great to have logging for utils.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_logging` with default `false`.

Start by locating the utils code and configuration entry points in the repository, then determine how production deployments currently handle output. Define the expected behavior of the new `enable_logging` option, including its default-off behavior, and verify it through the project's existing checks; no specific files or tests are named in the issue.
