Handle edge cases in retry

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

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

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

The issue does not identify a file, test, or entry point, and its title focuses on retry while the body requests type import. First reconcile that scope, then locate configuration handling for enable_import and establish expected behavior for its false default before adding coverage.
