For the vast majority of audio needs Rust is portable enough to cover x86, ARM, MIPS-based platforms. Probably 99% of users that need this kind audio/video multiplexing.
99% is not portable enough. Of 1B targets, 99% leaves 10 million targets unsupported. If each person has 100 targets (e.g. 30+ in your car), that means it doesn't work on something at least half of us depend on; and many others are only Tier 3. This is why I say "let's be honest, at least with ourselves". Pipewire that depends on Rust would be DOA. But Modern C++ works everywhere, and provides 90% of the safety, plus stuff Rust doesn't, yet, and other stuff Rust never will; and better performance than C.
