You can use a framework that abstracts all the WASM to JS communication for DOM access. There are many such framework already.

The only issue is that there’s a performance cost. Not sure how significant it is for typical applications, but it definitely exists.

It’d be nice to have direct DOM access, but if the performance is not a significant problem, then I can see the rationale for not putting in the major amount of work work it’d take to do this.
