"rewrite in X" request is a comon sign of immaturity. I'm guilty of it but eventually I learned that A) rewrites are rarely worth it B) it's disrespectful to ask others to scrap their code and rewrite it in my favorite language
One of my favorite apps at the moment seems like it could benefit from a rewrite, in part because core pieces have long standing bugs that may only be solved by someone doing the very deep dive a rewrite would entail. I thought long term it might be nice if it were written in Rust. But rather than suggest RIIR I considered writing a component of it in Rust myself. That would be educational for me and would bring something new to the "Rust ecosystem". Having written similar code before (in C++) I realized just how huge a task rewriting just a core component would be. It could take a decade or more to rewrite an entire program in any language even with all devs working on it.
Look at Servo. Hey, they started building a browser in Rust! And some of those components are useful in Firefox. But Servo itself might never become a fully functional browser. And that's a project from the folks that created Rust and Firefox. So maybe a response to RIIR could be "Yeah, when is Servo going to be done?"
