We decided to globally suppress this warning to unblock our Clang roll. But, that's something temporary, and we would like to suppress this warning in fine-grained level. All of the cases that we currently see are like `Case 2`. That's why I would to like get a clarification whether `Case 2` is considered a valid warning before we invest into suppressing in fine-grained level. TBH, that does not seem right to see different warnings between `Case 1` and `Case 2`. Is there any plan to change that?
