FWIW - when using a PR for a revert (or any change) that's not intended for precommit review, please include the `skip-precommit-approval` to make the intent clear (as documented here: https://llvm.org/docs/CodeReview.html#code-review-workflow - though I still need to commit a fix to that broken link/markup... ;))
