No, the person you were replying to was advocating for the intersection of ubiquitous features. C++ seems to be aiming for the union.
We also end up with C23, Fortran 2023, COBOL 2023, Scheme R7RS,... even those oldies embrace modern ideas.
It’s really not. The strawman that if we add a few features that have stood the test of time in every other language we’ll end up with C++ is just not true. Nobody is proposing adding SFINAE-based conditional compilation, rvalue references, multiple inheritance, or any of the million other Byzantine features that make C++ virtually impossible to use correctly. Adding sum types and a match statement does not necessarily start you down that path.
