No, please don't! The HTML DOM behind the canvas is necessary for accessibility.

I was referring to the app not the published web pages. Hehe

if you want accessibility you can build it natively accessible. keep the interface simple.

I agree with you in principle. But, needless to say, most developers don't design for accessibility above all else. We who care about accessibility need to meet developers and designers where they are, helping them incorporate accessibility into the way they're already building the UI or content, rather than tell them they need to do it a completely different way.

Haha yup. The interface you are seeing now is not the final one, you can be sure that in the future the application is going to be using wasm. Just like the guys at Figma are doing.
