WebAssembly expands on the ability to do client-side stuff and makes it more accessible, so my fear is that it will make it more common.

That's pretty much the entire difference. It's a difference of degree more than of kind. As I said, Javascript is making much of the web inaccessible to me, and WebAssembly, if it becomes popular, will only accelerate this loss.

I wonder how feasible a rendering proxy would be. It would run the JS in a simulated browser environment and return the HTML.

Interactivity would be tricky, but static HTML is better than a blank page.

Edit: Found something very similar, but it targets legacy browsers using clickable image maps rather than privacy/security.
