> C++ and Fortran are in active development, but to the best of my knowledge have neither "mod teams" nor the heightened level of drama that Rust seems to attract.

I don't know exactly how Fortran is developed, but C++ developed at the ISO which has its own flavour of bureaucracy.

And correct me if I'm wrong, but I also don't think that C++ has its own - sanctioned - community fora like Rust does.
