There was a very old ticket that was closed recently when a component was re-written in Rust. I can't find a link right this second, but if you could have told the future, it's kinda amusing. "Sorry, we'll fix this, but first we have to invent a new programming language. We'll get back to you in a decade."

Frankly, I think it's pretty amazing that bugs this old end up getting fixed. Not many projects live even live that long, let alone keep up their infrastructure...
