Add rate limiting for logging

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

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

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

The title asks for logging rate limiting, while the body asks for exporting utils and an enable_export configuration option. Start by locating the logging, utils export, and configuration entry points, then clarify which behavior is intended. Done should include the agreed feature, a default of false for enable_export if applicable, and tests or verification for the resulting behavior.
