But that's the thing, it's _not astonishing_. It _would_ be astonishing if we were abandoning typing Svelte. We're not. We're not even abandoning TypeScript -- the whole project will still run `tsc` and enforce complete type-safety, it just won't use the compiled output. This is _abandoning one syntax for another_ because one syntax doesn't require a build step and a huge toolchain to run and debug.
