I agree. I don't think the <accessible> tag is an improvement. In the common case, the same content can work as an accessible DOM and as fallback content. And that's also the model for other elements that use fallback content partly for accessibility purposes (e.g. <object>). I don't see the case for making canvas accessibility intrinsically more complicated.
