I am fairly certain the answer is "Yes". The DOM and other APIs have well-defined interfaces so it would likely be reasonable to wholesale export those to WASM.

I am fairly certain the answer is "Yes". The DOM and other APIs have well-defined interfaces so it would likely be reasonable to wholesale export those to WASM. If the timeframe is "ever" the answer is "yes". However I don't think it will be soon. I think the current biggest question is how garbage collection works with WASM. DOM nodes and many other resources are garbage collected. You need to define how WASM interfaces with that. (Does every object just get reference counted when passed to WASM and require an explicit free? Is there some sort of GC that traces over WASM memory?).
