Add configuration options for serialization

**Feature request**
It would be great to have analytics for data.

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

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

The issue names no files, tests, or entry points. Start by locating the configuration handling and serialization code, then clarify what analytics data and production behavior are required before implementation. Done should include a defined analytics behavior controlled by enable_analytics, defaulting to false, with coverage for both settings.
