I've been a professional C++ programmer for 24 years now, and neither I, nor anyone I've worked with over this period, used this ridiculous style.
This might be fixed in various languages/parsers by allowing a trailing comma (e.g. python).
At the end of the day, clang-tidy, black, gofmt, rustfmt all the things and let's never talk about comma placement again.
