Hey @nanddeepn, first, I want to thank you for all your hard work on the v9 major PRs. Your effort is really appreciated, and we're grateful for your dedication to these projects.

We’ve noticed some merging issues lately, which are expected with major PRs. However, when these PRs become difficult, closing and reopening new ones isn't ideal. It makes it hard for us to track reviews and isn’t sustainable long-term. An easy way out is, of course, creating a new PR on a new branch with the same changes, but this complicates our process and can be frustrating for both sides.

Remember, a PR is never beyond repair. @milanholemans wrote an extensive guide that should be very helpful in these situations. (#6164 (comment)) If you still need assistance, please don’t hesitate to ping @arjunumenon. He's available to sync and help resolve any issues you encounter.

Thanks again for your dedication and hard work on the v9 major PRs. We truly appreciate everything you're doing.
