Yes, because with <canvas> the feature has been carefully designed to have 
fallback content so that in browsers that don't support <canvas>, you can 
still see content that represents the same information (assuming authors 
provide it, of course). There's also an implementation of <canvas> for IE. 
And, probably most importantly, <canvas> is defined in a specification 
with exact parsing rules that define how it is to be treated, so if 
Microsoft decide to implement it, they can do so and ensure 
interoperability. None of this applies to sending SVG today as text/html.
