by giving it some thought and proposing some way to add the info required for
accessibility, to content in canvas. 

I suggested a crude idea of mapping area elements to focusable areas on a
canvas, which could have aria roles and states added to represent the many
interface elements that authors may develop using canvas.

may be totally unworkable, but it is a start of an idea.

Another issue that comes to mind in relation to the current canvas fallback is
that for any duplicate fallback that includes event handlers, there are going
to be interaction issues between those event handlers on the canvas and those
on the fallback. there is no mention of this currently, there needs to be a
robust method specified to resolve this.
