It seems like you provided a Pull Request description that is undefined or missing context. To create a meaningful summary for an advanced developer regarding a Pull Request for the Thanos project, I would need some specific details such as the purpose of the changes, key modifications, relevant files affected, any associated issues or discussions, and the overall impact on the project.

If you can provide the relevant details or a description of the Pull Request, I’d be more than happy to help summarize it!
