Update utils documentation

**Feature request**
It would be great to have notifications for types.

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

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

The issue names no files, tests, or entry points. Start by locating where configuration options are defined and how notifications and type handling currently work; clarify which types should trigger notifications before implementing `enable_notifications`, then verify that its default is `false` and that the requested production behavior is covered.
