That's like saying: "I don't care what the standard says!"

Sure, this is perfectly fine.

Only that you're not writing any C/C++ than, but something in the "gcc 12 language with some switches", or maybe the "LLVM 15 language with some switches", or something like that.

Well, if Visual Studio (or whatever Microsoft calls their compiler these days), and all known versions of gcc, and all known versions of LLVM all do something sane, then I'm not sure I care all that much about the theoretical possibility that some compiler someday might do something insane.
