Thanks for that! But I am following the below from "[Contributing to LLVM](https://llvm.org/docs/Contributing.html#how-to-submit-a-patch)"

_If you have received no comments on your patch for a week, you can request a review by ‘ping’ing the GitHub PR with “Ping” in a comment. The common courtesy ‘ping’ rate is once a week. Please remember that you are asking for valuable time from other professional developers._

If notifying via GitHub's mechanism is *also* expected, we should update the guideline.
