>And serialization seems to be far less costly than most people think. In the apps that I have written that make use of a off-main-thread architecture, structured clone has not been my bottle-neck.
If you're working within a render loop it does hurt, but I agree it isn't an issue for a typical use case. I think what detracts more is the ergonomics of the serialize/deserialize operations. Those are just largely seamless on the emscripten side. On the other hand, a full wasm/emscripten toolchain in your project arguably comes with its own ergonomic cost.
