FWIW, I fall exactly into that niche. I've never written a line of Rust in my life but am quite competent with Haskell and Ruby and have dabbled in at least half a dozen others. Seeing everyday `cargo` use made me think of bundler and the Future/Result type signatures were easy to map onto Async/Either and the like.

So yes, it's a long article but I didn't mind that in the least. Keep it up!
