Definitely. There's loads of value delivered by C++ implementations, including implementations of C++ and other languages. The language design of speed over safety mostly imposes a cost in developer / debugging time and fear of upgrading the compiler toolchain. Occasionally it shows up in real world disasters. I think we've got the balance wrong, partly because some engineering considerations derive directly from separate compilation. ODR no diagnostic required doesn't have to be a thing any more.
