If these people really have a great idea for what the future C++ should be like, then they should introduce that language all at once. Let us see their grand vision in one big package that can be embraced or rejected. This steady drip-drip-drip of half-baked features every few years is creating one hellish language.
I spend a lot of time in the Chromium source code and have seen plenty of boneheaded code, especially in places like Autofill where they seem to turn the newbies loose, but also in surprising places like V8, due to newbs using newfangled C++ "features" to do what worked perfectly well before in older idioms and was easier to read also.
Take for instance the function TryReduceFromMSB in v8/src/compiler/turboshaft/wasm-shuffle-reducer.cc -- do you see any reason that std::optional<uint8_t> max; couldn't just be a regular uint8_t? Let's name it 'max_used' also so the name is more descriptive and doesn't clobber the namespace.
