[boost] Boost.Extension - any plans?

Hi, I'd like to know if there are plans from it's author to submit Boost.Extension library for inclusion in boost? ( http://boost-extension.redshoelace.com/docs/boost/extension/index.html) Or any other plans? I remember the development was paused until some C++11 features would be available (I don't know which ones). But maybe I'm wrong. In my opinion, this library would be an excellent addition to boost.
