One major point of heartburn with Rust is that it comparatively lacks the diversity of ISA targets that C broadly does. I know some of this is because C is both relatively simple to write a basic compiler for that more or less just works (in comparison to something crazy like C++), and that's it's been around for a long time, but why isn't there more of a push to add at least all of the supported Debian ISAs to the Rust compiler?
Most people don't write a basic compiler for C either, "relatively simple" or no. Most people would rather add a new target to an existing compiler, which is much easier.
It's also "relatively easy" to add a new backend to Rust.
