That's an interesting perspective I'd not considered before. Maybe there are different "registers" of Rust, in the same sense that linguists talk about registers in human languages, where you use your language differently for different purposes. And thus, maybe if you're writing something that doesn't need to be screamingly fast absolutely all the time there's a register of Rust where putting lots of things in Rc<Box<T>> is completely acceptable, in much the same way that you might use a lot of impolite words around your friends but you don't in front of your employer.
