Yes: [Julia better rewritten in rust?](https://discourse.julialang.org/t/julia-better-rewritten-in-rust/84151)

One problem no one raised about Rust is that in BinaryBuilder we don’t have Rust toolchains for i686-w64-mingw32, aarch64-freebsd and riscv64-linux, because they are either unsupported by rustup or have incompatible runtimes with what we use. Which means we can’t compile Julia dependencies for those platforms, which would significantly complicate Julia build system there.
