I always assume that anyone that says that something is a false positive without providing any rigorous proof has confirmation bias and are sadly deluding themselves about their ability and the correctness of their code.
I said "probably" because the other messages from clang-tidy were so low quality obvious false positives too, a waste of time. I've already given the remaining warning a look and the code seemed fine to me. I didn't follow the whole massive linter output. Did you?
