I'm hoping C++ modules take off, because getting rid of naive textual inclusion enables mixing of code from different language versions, even if they're slightly incompatible. It would enable C++ to have an Edition concept like Rust, and be able to start removing warts and poor defaults from the language, without breaking old code, and without needing the whole world to upgrade at once (well, except the modules adoption).
