As a long-time Rust guy, this article makes little sense to me. It is surely possible for any language to target Rust, but unless the semantics of that language are an unusually close match to Rust's then you're going to have to pull off some gymnastics. LLVM IR is actually designed to be a decent compilation target for a wider variety of languages (though I wish there was more documentation on what is and is not UB), but even LLVM IR is going to start looking like a poor choice of a target the farther your language is from C++.
