I wouldn't say that Windows/ARM is that obscure anymore, not when there are quite a few laptops on the market with it. But, by the same token, it's not an exotic dev platform. The compilers are there, the libraries already have to compile on Linux/ARM as well as Windows/x64, which means that the same C code will usually compile and work just fine on Windows/ARM. So yeah, no, that's not a valid reason to rewrite it in Rust.
