Also note Mikko's response to the canvas-requirement survey:

The main rationale behind HTML5 is Rich Web Applications, and vector graphics play a major role in this application scope.

My only major concern about the canvas solution to this requirement is performance in mobile platforms. The main reason is using ECMAScript in the drawing loop.

Hopefully the next version ECMAScript will enable better performing implementations (although the API should be checked wheather it can be typed). On the other hand, SVG has not been proven to perform any better in real world applications.

it's not really clear that this belongs in the issues list. Perhaps we'll figure out a relate issue, but for now, we're closing this.
