It appears that the details of the Pull Request you referred to are undefined. To create a summary for an advanced developer regarding a Pull Request in the Thanos project, I would typically need information such as:

• The title of the Pull Request
• A description of the changes proposed
• The files modified
• Any relevant context about why the changes are necessary
• Gathered feedback or discussion from other contributors
• Related issues the Pull Request addresses

If you can provide any specific details or context regarding the Pull Request, I’d be happy to help you craft a detailed summary!
