On the conceptual level it is far from clear to me if such a framework is needed to begin with. In the Scope section Vicente explicitly states that his library "is not particularly concerned with cases of...". Those "excluded" cases happen to be the most tricky/used/needed cases.

I never had a need for such a generic type-to-type conversion framework. Obviously, it's my own limited experience and it can be vastly different for others.
Vladimir's concerns resonate very well with my feelings towards Boost.Conversion. If I understand the spirit of the library right, it introduces a new concept with an associated operation, which can be used in generic algorithms. But I never needed such a thing and can't come up with a real-life example where I would use it. Roman Perepelitsa.
