To triple check this grouping behavior in clang, there's a utility called `diagtool`. $ diagtool tree will print the hierarchy of diagnostics and color code them to explain whether they're on/off by default or not-implemented-but-recognized. For the above two -Wformat-* warnings, note that clang does not yet implement those. I've filed https://github.com/llvm/llvm-project/issues/64871 to track that. -- Thanks, ~Nick Desaulniers
