Are we certain all of the cases are unused, or are we just not exhaustively
testing them?

I see one at least (the bottom one) where a third case is identified as
possible if extract on a black node with a black child.  Might be a problem
when you create a tree, extract some nodes, add some nodes, extract some more
nodes?  I'm not convinced that all of these cases are redundant.
