Thanks! In working on WebAssembly/component-model#345 one thing I want to consider though is the roadmap for how it's going to be implemented. For example I think it would best to avoid situations where half the system works and half the system doesn't due to the order in which things were done. Do you have an idea of how much of he rest of wasm-tools/wasmtime/etc need to be updated for this change? I would naively expect that wasmparser validation might need changing as well but not much else other than that. I wanted to see if you had plans already made though perhaps.

fix wasmparser and wasm-smith

I think that's all we needed. I tried locally with my wit file. Both wasm-tools and wac (after a bump) are working as expected.
