Wasmer's approach hints at faster cold starts and better overall performance; the benchmarking against pyodide is a bit unclear, and it's unclear to me whether that would make or break viability for a use case like this.
But one thing this does make possible is if your arbitrary script is actually a persistent server, you can deploy that to edge servers, and interact with your arbitrary scripts over the network in a safe and sandboxed way!
