This really should be a WebAssembly runtime so that the same computations can run on different platforms and devices.

I tend to use Wasmtime, V8, WAMR, and browsers. The point of WebAssembly is that there are many runtimes.
So even if there are many WebAssembly runtimes, there's only one that mostly cover the POSIX semantics
You're not helping the negative reputation of Wasmer that's out there with this unprompted promotion.
If you think my comments do not add value, you can simply skip interacting. They might still be useful for others though :)
