Add rate limiting for timeout

**Description**
Currently core lacks proper import support.

**Proposed solution**
Add configurable import with sensible defaults.

**Priority**: Low/Medium

The title asks for rate limiting around timeouts, while the description asks for configurable import support, and no files, tests, or entry points are named. First clarify which behavior is intended and locate the relevant timeout or import code; done should include configurable behavior with sensible defaults and a testable outcome agreed in the issue.
