My expectation would be that any GnomeCanvas display will require
substantial custom accessibility work - for example we have no idea if
a GdkPixbuf item is conveying interesting information or just some
irrelevant decoration (I suspect in most cases it's the latter).
Basically GnomeCanvas is similar to GDK in that it's a way to draw,
there's no high-level semantics...

That said I'm sure we could have a way to get the pixbuf from a pixbuf
item (if g_object_get() won't work), I just doubt it gets us very far.
