I agree with the issue, however regarding:

> for instance any WASM blob that’s hosted on Github pages cannot use threading

I think you could use what @tobyjaffey is using here [Framebuffer and Audio WASM demos](https://ziggit.dev/t/framebuffer-and-audio-wasm-demos/7146), [coi-serviceworker](https://github.com/ringtailsoftware/zig-wasm-audio-framebuffer#cors-cross-origin-resource-sharing):

But it seems you can’t avoid the reload on github pages.
