It seems that the Pull Request you mentioned does not have any defined content or context. To create a meaningful summary for an advanced developer, I would need specific details about the changes proposed in the Pull Request or its intended functionality. Typically, a summary would include:

  1. Title/Description of the Changes: Briefly outline what the PR is aiming to change or add.
  2. Motivation: Explain why these changes are necessary or beneficial for the Thanos project.
  3. Key Modifications: Point out the main files or components that are impacted, along with a high-level overview of the code changes.
  4. Testing and Validation: Mention how the changes were tested, including any new tests added or changes to existing tests.
  5. Backward Compatibility: Discuss if there are any breaking changes introduced by this Pull Request.
  6. Related Issues: Reference any related issues or discussions that this PR addresses.

If you can provide more details regarding the content of the Pull Request, I can definitely help in drafting a comprehensive summary.
