Yeah I'm really keen for that - though I think compiling a bunch of dependencies into individual wasm modules will be kind of awful to use in practice.

Apparently in firefox they've been compiling some of their dependencies using wasm, then translating the wasm back to C. The end effect of all that is that it gives C code wasm's sandboxing and safety. I wonder what it would look like to do that without needing wasm as a middle step.
