Here is an example of an application using getImageData which would clearly benefit from HD, but it's not obvious that async would be useful:

This is off topic, but I disagree. The only thing that you want is a rasterized result at the end. In the meantime it can be object and vector based (and in high resolution) on the screen. This would even allow you to create high resolution PNGs. I see a lot more benefits, but we can discuss it on another place.
