E.g. it feels like a lot of over-engineering just to get 2x faster string marshalling, and this is only important for exactly one use case: for creating a 1:1 mapping of the DOM API to WASM. Most other web APIs are by far not as 'granular' and string heavy as the DOM.
E.g. if I mainly work with web APIs like WebGL2, WebGPU or WebAudio I seriously doubt that the component model approach will cause a 2x speedup, the time spent in the JS shim is already negligible compared to the time spent inside the API implementations, and I don't see how the component model can help with the actually serious problems (like WebGPU mapping GPU buffers into separate ArrayBuffer objects which need to be copied in and out of the WASM heap).
It would be nice to see some benchmarks for WebGL2 and WebGPU with tens-of-thousands of draw calls, I seriously doubt there will be any significant speedup.

It's still not a great idea IMHO ;)
