Sounds and looks like it was fun to implement, but is there a motivating use case? Or is it more for technical/hacking interest?
I think this may become the basis of an operating environment where you do not have to concentrate on "how to run" something. Instead, you get straight to the job of deciding "what to run" so you can reap the benefits in no time without all the devops and SaaS drama.
The closest contemporary thing is fly.io, but recently they became less strategic and more opinionated. Another attempt is sandstorm.io but it was abandoned by the original authors. So... maybe WASM and the initiatives like WASIX will give it to us?
Sandstorm is still maintained:
