Consider deprecating old store API

**Description**
Currently lib lacks proper filtering support.

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

**Priority**: Low/Medium

Start by locating the current store API under lib and reading how filtering is handled today. Clarify whether the intended change is configurable filtering, deprecation of the old API, or both, including the expected defaults. Done should mean the agreed behavior is implemented and covered by the relevant existing checks.
