It's about time. Critical infrastructure still written in C - particularly code that parses data from untrusted sources - is technical debt that is only going to get worse over time. It's not as if Rust is that much more difficult to write than C. Rust is explicitly designed to be what you'd get if you were to re-create C knowing what we know now about language design and code safety.
If 32-bit x86 support can be dropped for pragmatic reasons, so can these architectures. If people really, really want to preserve these architectures as ongoing platforms for the future, they need to step up and create a backend for the Rust toolchain that supports them.
