Improve error messages in models

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

**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 helper implementation and configuration handling, then clarify which analytics are required for production deployments and how they should be collected. Done should include the `enable_analytics` option defaulting to `false`, plus an agreed behavior and tests for the requested analytics.
