The only thing I ever proposed for the expansion of std::tuple was to add operator[] which takes a runtime index and returns a std::variant (possibly with extension of std::variant to allow for references). The internal representation would not be changed (no ABI break!). And if you don’t use operator[] you don’t pay for it: zero abstraction principle: You don’t pay for what you don’t use!
