Add Views Handlers for Views of Type Node Revision

I'm working on a view that lists all revisions that a person has made to various nodes over time. This is a "Node Revision" view, as opposed to the standard "Node" view. Unfortunately the Workflow Views handlers don't appear to work for this type of view, so I can't add in a field that displays the current workflow state of the node.

Would someone consider adding this in? I'm still learning about how to code for Views, so I'm not at a point to where I can write a patch for this myself yet.
