One possible use-case is a system like Inferno[0] (the plan9-like operating system). Since, on that OS, you can "mount" CPUs from other machines over the network[1], you either need to make sure all of your machines have the same CPU architecture (including additional instruction sets lest you end up with AVX512 code trying to run on an Intel processor), or you use a non-compiled language. Inferno went with the latter and introduced Limbo[2] for that purpose, but with webasm we could use any language and still leverage all the great tooling being written for it.
