Consider deprecating old store API

**Problem**
When working with hooks, the error messages could be more descriptive.

**Suggestion**
Improve error handling and add detailed error messages.

**Context**
This would help with debugging and maintenance.

Start by locating the hooks and the old store API referenced in the issue. Read how their current errors are produced and review the surrounding call paths before determining the intended deprecation scope. Done should include a decided API direction and more descriptive error messages, but the issue does not name files or tests.
