We don't have a scene-graph object.
 
I understand that there is a concern that authors will accidentally change
the settings and that changing the settings used in a particular context/
canvas pair is expensive. But I don't see how a middleman object would
help. If an author could accidentally use different settings when binding
a context to a canvas, why couldn't an author accidentally use a different
middle man object?
It's not a middle-man, it's a drawing buffer. Using a different drawing buffer is cost free. Creating/changing one isn't.
