The patch is ok to me. Your arguments are convincing. You can commit it into the trunk. Because it is a sensitive LRA code (the code was related to many PRs and it was changed many times), there is a possibility that it will introduce some new PRs. So wee need to keep attention to it after you commit the patch. Thank you for working on the PR.
