I third Benoit's opinion, but would understand if it needed to be
removed. Having some mixed projects, and the ABI incompatible changes
in the Vector3d etc typedefs would perhaps make it harder for us, but
we could also require 3.0-3.1 if necessary. We are working on moving
everything over, but these things take time.
