If a standard doesn't consider practical contraints it will never become a  
standard as it will not be implemented.

There are lots of potential problems, such as how it would interact with  
plugins or some video if both render to the same context. Or if you allow  
it on elements such as <div> what would happen if text resizing caused the  
canvas to rescale, et cetera.
