I didn't know that that was your proposal. This thread was just for ero sized images. We have interop on exceptions when the image is not in the ready state [1] so we shouldn't change that (even though I agree there shouldn't have been an exception in the first place) For exception-free drawimage calls, people can use the ImageBitmap class. 1: http://www.whatwg.org/specs/web-apps/current-work/multipage/the-canvas-element.html#check-the-usability-of-the-image-argument
