It seems that the Pull Request you’re referring to is undefined, meaning there isn’t any specific information provided about it. To create a concise summary, I would need details regarding the changes being proposed, the motivation behind the PR, any related issues it addresses, and the overall impact on the Thanos project.

If you could provide specifics about the Pull Request, such as the description, purpose, or any relevant comments, I could help you summarize it effectively for an advanced developer.
