I don't think there is a rush. The 3.0.0 alphas still support
interfaces deprecated in 0.9.8 (released 2005). AFAICT, nothing tagged
under this API compatibility scheme has ever been removed. If they
started doing so, they would presumably do it step by step at the tail
end, which would still give us several steps before it catches up with us.
