I would go so far as to say that it is unacceptable for a serious
library. Every extra requirement on client code that isn't absolutely
necessary will dramatically reduce the potential userbase of your code
unless it brings with it a set of stong benefits. And I think that
you'll be hard pressed to show that this inheritance requirement brings
ANY benefits, much less compelling ones.

That said, I would really love to see a library like this in boost, and
I encourage Franck to push forward with development.
