So why aren't people just shipping straight up LLVM intermediate language VMs and instead go through wasm?

Incidentally, would you consider wasm as a destination language for virtual machines for obfuscation? I.e. is it reasonable enough to implement it all in about a week? Plus I fear like the decompilation/disassembly tooling might be there too soon for it to be a real viable option, but maybe nobody's been working on that yet.
