You could also start removing the heavy-to-maintain parts, e.g. by not 
supporting stage10 or stage20 anymore. (I have no overview, how strong 
each stage currently influences the code base).
Projects that got stuck at EIGEN2_SUPPORT_STAGE10_FULL_EIGEN2_API are 
still allowed to stay with Eigen3.1 if they are unwilling to port ...
