Consider deprecating old store API

**Description**
Currently routes lacks proper export support.

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

**Priority**: Low/Medium

Start by tracing the routes and the existing store API mentioned in the issue. Clarify whether the goal is to deprecate the old API, add configurable export support, or both, then identify the relevant entry points and existing tests. Done should include documented defaults and coverage for the export behavior and any deprecation path.
