Let's see more $foo implemented in rust.
But you've missed a couple of reasons why Rust rewrites are popular. Rewriting in Rust is proven path to better performance (Python codebases pandas -> polars, black -> ruff) or better security. C/C++ codebases like FreeType being rewritten in Rust for security (https://developer.chrome.com/blog/memory-safety-fonts). What should people looking for performance or security do to mollify you?
You are asking why aren't completely new ideas being implemented in Rust? They are. Check out https://rerun.io. I could be mistaken, but I haven't seen anything similar to rerun. And that was implemented in Rust. Maybe these aren't visible because there genuinely are so few things that are completely novel.
