Azure Devops Extension Issue

We currently have the WIQL Editor Azure DevOps extension (developed by Otto Streifel) installed in our ADO. The extension is now marked as unpublished, which makes it non‑compliant from a governance perspective.
Before removing it from our Azure DevOps organisation, we need to clearly understand the impact.
Query / Clarification required:
Could you please confirm whether removing the unpublished WIQL Editor extension will result in any loss or impact to:

Existing saved queries (My Queries / Shared Queries)
Query folders or query permissions
Any other Boards or work‑item–related data within Scrum projects

Our understanding is that the WIQL Editor is primarily an authoring / execution tool and that removing it should not affect existing queries, but we would appreciate confirmation from the maintainers before proceeding.

Environment:

Azure DevOps Services
Scrum projects using Boards and Queries
Thanks in advance for your guidance.

No files or tests are identified in the issue. Start by reviewing how the extension stores or accesses saved queries, folders, permissions, and work-item data in Azure DevOps; done means documenting the confirmed effects of uninstalling the unpublished extension for each listed area.
