It seems there is no specific information or details provided about the Pull Request you’re referring to for the Thanos project. To create a summary suitable for an advanced developer, I would need details such as the objectives of the Pull Request, the changes made, the relevant files or components affected, any potential impact on the project’s functionality, and any discussions or feedback associated with it.

If you can provide more context or specifics about the Pull Request, I would be happy to help you create a comprehensive summary!
