Hmmm I'm not sure if it could be properly used to circumvent ad blocking, after all the ads will still probably come from a separate request which one could block.

However I do see it being used for web apps that prioritise performance--in terms of providing a smooth experience, rather than load times. I think Figma already does that (through emscripten or wasm, I'm not sure); for it to be more widespread, only the tooling has to catch up (e.g. React Native).
