This story is about moving away from WASM for an application that's unsuitable for it. It's not really about Rust.

It's not an unsuitable application for WASM. They could've drastically reduced the WASM boundary impact if instead of mapping to JSON in Rust they streamed out structured bytes to JS then mapped to JSON there. And the streaming fix was language independent.

So it's more so a story about architectural mistakes.
