This is fascinating to me because I once tried to take a (vaguely) similar approach to generate a procedural city layout, taking a voronoi diagram, and then doing some modified flood fills to create buildings within the city while leavings streets. It feels to me like their approach could be used for this as well, since there's of course nothing that requires it to only be used for generating floor plans.
