Thanks for the input, and I completely agree in the value of all of these aspects, just not so much for prototyping. Tooling and packaging disappear with a sufficiently good prototyping environment (and Cargo doesn't completely eliminate this in my experience anyway), Rust's type system means also working with the borrow checker which is not useful for data modelling (outside of safety concerns), large refactorings aren't necessary in small prototypes (even as things change). You're right that it's easier to grow a codebase organically from a good starting point, and Rust will offer that, but I'm not sure that's the right focus for rapid prototyping. The aim is not about setting solid foundations, it's about testing ideas. Rust is nice, don't get me wrong. I don't disagree with any of these points. I just think that they're all in the mode of improving "traditional" backend development, not in the mode of making rapid prototyping as good as it can be.
